[java] Error - trustAnchors parameter must be non-empty

I'm trying to configure my e-mail on Jenkins/Hudson, and I constantly receive the error:

java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be
    non-empty

I've seen a good amount of information online about the error, but I have not gotten any to work. I'm using Sun's JDK on Fedora Linux (not OpenJDK).

Here are a few things I've tried. I tried following the advice from this post, but copying the cacerts from Windows over to my Fedora box hosting Jenkins didn't work. I tried following this guide as I'm trying to configure Gmail as my SMTP server, but it didn't work either. I also tried to download and move those cacert files manually and move them over to my Java folder using a variation of the commands on this guide.

I am open to any suggestions as I'm currently stuck right now. I have gotten it to work from a Windows Hudson server, but I am struggling on Linux.

This question is related to java hudson jakarta-mail jenkins

The answer is


I had this issue when trying to use Maven 3, after upgrading from Ubuntu 16.04 LTS (Xenial Xerus) to Ubuntu 18.04 LTS (Bionic Beaver).

Checking /usr/lib/jvm/java-8-oracle/jre/lib/security showed that my cacerts file was a symbolic link pointing to /etc/ssl/certs/java/cacerts.

I also had a file suspiciously named cacerts.original.

I renamed cacerts.original to cacerts, and that fixed the issue.


If you experience this on Ubuntu with JDK9 and Maven, you can add this JVM option - first check if the path exists:

-Djavax.net.ssl.trustStore=/etc/ssl/certs/java/cacerts

If the file is missing, try to install the ca-certificates-java as someone noted:

sudo apt install ca-certificates-java

System.setProperty("javax.net.ssl.trustStore", "C:\\Users\\user-id\\Desktop\\tomcat\\cacerts");
System.setProperty("javax.net.ssl.trustStorePassword", "passwd");

You have to add the above two lines to your code. It is not able to find the truststore.


Another reason for this is it's actually a valid error. Some nefarious Wi-Fi hotspots will mess with certificates and man-in-the-middle attack you to do who knows what (run away!).

Some large employers will do this same trick, especially in sensitive network zones so they can monitor all the encrypted traffic (not great from end user perspective, but there may be good reasons for this).


The error tells that the system cannot find the truststore in the path provided with the parameter javax.net.ssl.trustStore.

Under Windows I copied the cacerts file from jre/lib/security into the Eclipse install directory (same place as the eclipse.ini file) and added the following settings in eclipse.ini:

-Djavax.net.ssl.trustStore=cacerts
-Djavax.net.ssl.trustStorePassword=changeit
-Djavax.net.ssl.trustStoreType=JKS

I had some troubles with the path to the cacerts (the %java_home% environment variable is somehow overwritten), so I used this trivial solution.

The idea is to provide a valid path to the truststore file - ideally it would be to use a relative one. You may also use an absolute path.

To make sure the store type is JKS, you would run the following command:

keytool -list -keystore cacerts

Keystore type: JKS
Keystore provider: SUN

Note: because certificates have expiration dates, or can become invalid for other reasons, do check from time to time if the certificates in cacerts are still valid. You would usually find the valid versions of the certificates in the latest builds of jdk.


I got this error when using a truststore which was exported using a IBM Websphere JDK keytool in #PKCS12 format and trying to communicate over SSL using that file on an Oracle JRE.

My solution was to run on an IBM JRE or convert the truststore to JKS using an IBM Websphere keytool, so I was able to run it in an Oracle JRE.


I encountered this problem with the Android SDK sdkmanager. For me this solution worked:

  1. Go to /usr/lib/jvm/java-8-oracle/jre/lib/security/
  2. Replace cacert with cacert.original

The cacert file was a tiny one (22B). I have installed oracle-java8-installer from ppa:webupd8team/java (according to this manual: https://docs.nativescript.org/start/ns-setup-linux).


I ran into this solution from blog post Fixing the trustAnchors problem when running OpenJDK 7 on OS X:

Fixing the trustAnchors problem when running OpenJDK 7 on OS X. If you're running OpenJDK 7 on OS X and have seen this exception:

Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors
    parameter must be non-empty

There's a simple fix. Just link in the same cacerts file that Appleā€™s JDK 1.6 uses:

cd $(/usr/libexec/java_home -v 1.7)/jre/lib/security
ln -fsh /System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security/cacerts

You need to do this for every OpenJDK version you have installed. Just change -v 1.7 to the version you want to fix. Run /usr/libexec/java_home -V to see all the JREs and JDKs you have installed.

Perhaps the OpenJDK guys could add this to their install scripts.


I ran into this exact problem on OS X, using JDK 1.7, after upgrading to OS X v10.9 (Mavericks). The fix that worked for me was to simply reinstall the Apple version of Java, available at http://support.apple.com/kb/DL1572.


I'm a fan of portability, so I don't install java, just download the tar.gz and export some values in the path and everything works.

I fought with this issue and no solution (install or update operative systems certs) worked for me.

Error in my case was clear: empty cacerts inside my jdk.

I don't know why, but my jdk.tar.gz had an empty cacerts file

/../some_openjdk/jre/lib/security/cacerts : 32 bytes

Downloaded from:

Fix

After several attempts I found a correct jdk.tar.gz with a cacerts file with size 101 KB

I downloaded this open jdk from https://github.com/AdoptOpenJDK/openjdk8-upstream-binaries

I found this url in this Dockerfile :


None of solutions that I found on the Internet worked, but a modified version of Peter Kriens's answer seems to do the job.

First find your Java folder by running /usr/libexec/java_home. For me it was the 1.6.0.jdk version. Then go to its lib/security subfolder (for me /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security).

Then delete the cacerts file if there is one already and search for one on the system with sudo find / -name "cacerts". It found multiple items for me, in versions of Xcode or other applications that I had installed, but also at /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib/security/cacerts which I chose.

Use that file and make a symbolic link to it (while inside the Java folder from before), sudo ln -fsh "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib/security/cacerts", and it should work.

I have both - Java from Apple's 2017-001 download (https://support.apple.com/kb/dl1572 - I assume that's where the correct certificates are from) and Oracle's one installed on Mac OS X v10.12 (Sierra).


This fixed the problem for me on Ubuntu:

sudo /var/lib/dpkg/info/ca-certificates-java.postinst configure

(found here: https://bugs.launchpad.net/ubuntu/+source/ca-certificates-java/+bug/1396760)

ca-certificates-java is not a dependency in the Oracle JDK/JRE so this must be explicitly installed.


On Ubuntu:

sudo apt install ca-certificates-java

or

sudo apt-get install ca-certificates-java

sorted it for me.


I faced this problem while running a particular suite of Android for testing on Ubuntu 14.04 (Trusty Tahr). Two things worked for me as suggested by shaheen:

sudo update-ca-certificates -f

sudo /var/lib/dpkg/info/ca-certificates-java.postinst configure

on ubuntu 14.04 with openjdk 11 from ppa:openjdk-r/ppa this worked for me:

in java.security change keystore type to

keystore.type=jks

then:

sudo dpkg --purge --force-depends ca-certificates-java
sudo apt-get install ca-certificates-java

when you check if it worked, be sure you are not using any daemon with old java still running (eg. --no-daemon option for gradle)

this bug describes everything nicely and will help you understand what's going on https://bugs.launchpad.net/ubuntu/+source/ca-certificates-java/+bug/1739631


I've had lot of security issues after upgrading to OS X v10.9 (Mavericks):

  • SSL problem with Amazon AWS
  • Peer not authenticated with Maven and Eclipse
  • trustAnchors parameter must be non-empty

I applied this Java update and it fixed all my issues: http://support.apple.com/kb/DL1572?viewlocale=en_US


You must add the cert file to your java keystore Go to chrom , open the website , save the certificate in txt format

Go to cmd> keytool -import -trustcacerts -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit -alias Root -import -file Trustedcaroot.txt

https://knowledge.digicert.com/solution/SO4085.html

This has worked like a charm


I found yet another reason for this error, which is not related to Ubuntu.

I tried setting up mutual TLS in a Spring boot 2 app and ran into this issue after using a truststore that had only a private key entry and no trusted certificate entry.

This is my Spring Boot TLS configuration

server.port=8443
server.ssl.key-alias=oba-tls
server.ssl.key-password=mypw
server.ssl.key-store-password=mypw
server.ssl.key-store=classpath:keys/tls-keystore.pfx
server.ssl.key-store-type=PKCS12
server.ssl.enabled=true
server.ssl.client-auth=need

server.ssl.trust-store=classpath:keys/truststore.pfx
server.ssl.trust-store-password=mypw
server.ssl.trust-store-type=PKCS12
server.ssl.ciphers=ECDHE-RSA-AES128-GCM-SHA256,ECDHE-RSA-AES256-SHA384
server.ssl.protocol=TLS
server.ssl.enabled-protocols=TLSv1.2

For generating truststore.pfx I had to use the following commands to make it work.

openssl req -newkey rsa:2048 -nodes -keyout private.key -x509 -out cert.crt

keytool -importcert -alias oba-trust -file cert.crt -keystore truststore.jks

keytool -importkeystore -srckeystore truststore.jks -destkeystore truststore.pfx -srcstoretype JKS - deststoretype PKCS12 -deststorepass yourpassword

On Ubuntu 18.04 I needed to use OpenJDK 1.7 for the maintenance of an old project. I downloaded the binary package. But when I executed my script on it I got the same error.

The solution was to remove the cacerts file of the downloaded JDK in the jre/lib/security folder and then to create it as symlink to the systems cacerts file in /etc/ssl/certs/java/:

sudo ln -s /etc/ssl/certs/java/cacerts /path/to/downloaded/java/jre/lib/security/cacerts


I have faced with the issue while importing a Gradle project in IntelliJ IDEA 14. A solution was using a local copy of Gradle instead of a wrapper from the project directory.


Fall into this using Amazon SDK v2, Windows 10 and JDK8. Amazon SDK was complaining about credentials loading.
I solved this by replacing the security/cacert file of JDK8 by the JDK11 one.


Removing the ca-certificates-java package and installing it again worked for me (Ubuntu MATE 17.10 (Artful Aardvark)).

sudo dpkg --purge --force-depends ca-certificates-java

sudo apt-get install ca-certificates-java

Thank you, jdstrand: Comment 1 for bug 983302, Re: ca-certificates-java fails to install Java cacerts on Oneiric Ocelot.


I had this error message on Java 9.0.1 on Linux. It was due to a known bug of the JDK, where the cacerts file is empty in the .tar.gz binary package (downloaded from http://jdk.java.net/9/).

See the "known issues" paragraph of JDK 9.0.1 Release Notes, saying "TLS does not work by default on OpenJDK 9".

On Debian/Ubuntu (and probably other derivaties), a simple workaround is to replace the cacerts file with the one from the "ca-certificates-java" package:

sudo apt install ca-certificates-java
cp /etc/ssl/certs/java/cacerts /path/to/jdk-9.0.1/lib/security/cacerts

On Red Hat Linux/CentOS, you can do the same from the "ca-certificates" package:

sudo yum install ca-certificates
cp /etc/pki/java/cacerts /path/to/jdk-9.0.1/lib/security/cacerts

In Ubuntu 12.10 (Quantal Quetzal) or later, the certificates are held in the ca-certificates-java package. Using -Djavax.net.ssl.trustStore=/etc/ssl/certs/java/cacerts will pick them up regardless of what JDK you're using.


On Ubuntu 18.04 the root cause is a conflict between openjdk-11-jdk (which is default) and other packages depending on it. It has already been fixed in Debian and will be included in Ubuntu shortly. Meanwhile the simplest workaround is to demote your java to version 8. Other solutions employing ca-certificates-java are much more complicated.

First remove conflicting packages:

sudo apt-get remove --purge openjdk* java-common default-jdk
sudo apt-get autoremove --purge

Check whether you successfully removed all related packages by:

sudo update-alternatives --config java

The system shall prompt you there is no Java available to config, otherwise this workaround fails.

Then reinstall required packages:

sudo apt-get install openjdk-8-jdk

For the record, none of the answers here worked for me. My Gradle build started failing mysteriously with this error, unable to fetch HEAD from Maven central for a particular POM file.

It turned out that I had JAVA_HOME set to my own personal build of OpenJDK, which I had built for debugging a javac issue. Setting it back to the JDK installed on my system fixed it.


I also encountered this on OS X after updating OS X v10.9 (Mavericks), when the old Java 6 was being used and tried to access an HTTPS URL. The fix was the inverse of Peter Kriens; I needed to copy the cacerts from the 1.7 space to the location linked by the 1.6 version:

(as root)
umask 022
mkdir -p /System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security
cp $(/usr/libexec/java_home -v 1.7)/jre/lib/security/cacerts \
    /System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security

On Red Hat Linux I got this issue resolved by importing the certificates to /etc/pki/java/cacerts.


I got the same error when sending emails, but NOT always. In my case I've changed one line of code to get a new Session object every time:

MimeMessage message = new MimeMessage(Session.getDefaultInstance(props, authenticator));

to

MimeMessage message = new MimeMessage(Session.getInstance(props, authenticator));

Since then sending e-mails works every time.

The error I got:

javax.mail.MessagingException: Could not convert socket to TLS;
nested exception is: javax.net.ssl.SSLException:
java.lang.RuntimeException: Unexpected error:
java.security.InvalidAlgorithmParameterException: the trustAnchors

javax.mail.Transport.send(Transport.java:124)


You may also encounter this error after upgrading to Spring Boot 1.4.1 (or newer) because it brings along Tomcat 8.5.5 as part of its dependencies.

The problem is due to the way that Tomcat deals with the trust store. If you happen to have specified your trust store location as the same as your keystore in the Spring Boot configuration, you'll likely get the trustAnchors parameter must be non-empty message when starting the application.

server.ssl.key-store=classpath:server.jks
server.ssl.trust-store=classpath:server.jks

Simply remove the server.ssl.trust-store configuration unless you know that you need it, in which case consult the links below.

The following issues contain more details about the problem:


EJP basically answered the question (and I realize this has an accepted answer), but I just dealt with this edge-case gotcha and wanted to immortalize my solution.

I had the InvalidAlgorithmParameterException error on a hosted Jira server that I had previously set up for SSL-only access. The issue was that I had set up my keystore in the PKCS#12 format, but my truststore was in the JKS format.

In my case, I had edited my server.xml file to specify the keystoreType to PKCS, but I did not specify the truststoreType, so it defaults to whatever the keystoreType is. Specifying the truststoreType explicitly as JKS solved it for me.


Marquis of Lorne's answer is accurate, I'm adding some info for debugging purposes:

To debug this issue (I wrote about it with more details in here) and understand what truststore is being used (or trying to use) you can add the property javax.net.debug=all and then filter the logs about truststore. You can also play with the property javax.net.ssl.trustStore to specify a specific truststore. For example :


    java -Djavax.net.debug=all -Djavax.net.ssl.trustStore=/Another/path/to/cacerts -jar test_get_https-0.0.1-SNAPSHOT-jar-with-dependencies.jar https://www.calca.com.py 2>&1| grep -i truststore


In Ubuntu 18.04, this error has a different cause (JEP 229, switch from the jks keystore default format to the pkcs12 format, and the Debian cacerts file generation using the default for new files) and workaround:

# Ubuntu 18.04 and various Docker images such as openjdk:9-jdk throw exceptions when
# Java applications use SSL and HTTPS, because Java 9 changed a file format, if you
# create that file from scratch, like Debian / Ubuntu do.
#
# Before applying, run your application with the Java command line parameter
#  java -Djavax.net.ssl.trustStorePassword=changeit ...
# to verify that this workaround is relevant to your particular issue.
#
# The parameter by itself can be used as a workaround, as well.

# 0. First make yourself root with 'sudo bash'.

# 1. Save an empty JKS file with the default 'changeit' password for Java cacerts.
#    Use 'printf' instead of 'echo' for Dockerfile RUN compatibility.
/usr/bin/printf '\xfe\xed\xfe\xed\x00\x00\x00\x02\x00\x00\x00\x00\xe2\x68\x6e\x45\xfb\x43\xdf\xa4\xd9\x92\xdd\x41\xce\xb6\xb2\x1c\x63\x30\xd7\x92' > /etc/ssl/certs/java/cacerts

# 2. Re-add all the CA certs into the previously empty file.

Status (2018-08-07), the bug has been fixed in Ubuntu Bionic LTS 18.04.1 and Ubuntu Cosmic 18.10.


Ubuntu 1770553: [SRU] backport ca-certificates-java from cosmic (20180413ubuntu1)

Ubuntu 1769013: Please merge ca-certificates-java 20180413 (main) from Debian unstable (main)

If the issue continues after this workaround, you might want to make sure that you're actually running the Java distribution you just fixed.

$ which java
/usr/bin/java

You can set the Java alternatives to 'auto' with:

$ sudo update-java-alternatives -a
update-alternatives: error: no alternatives for mozilla-javaplugin.so

You can double-check the Java version you're executing:

$ java --version
openjdk 10.0.1 2018-04-17
OpenJDK Runtime Environment (build 10.0.1+10-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)

There are alternative workarounds as well, but those have their own side effects which will require extra future maintenance, for no payoff whatsoever.

The next-best workaround is to add the row

javax.net.ssl.trustStorePassword=changeit

to the files

/etc/java-9-openjdk/management/management.properties
/etc/java-11-openjdk/management/management.properties

whichever exists.

The third least problematic workaround is to change the value of

keystore.type=pkcs12

to

keystore.type=jks

in the files

/etc/java-9-openjdk/security/java.security
/etc/java-11-openjdk/security/java.security

whichever exists, and then remove the cacerts file and regenerate it in the manner described on the last row of the workaround script at the top of the post.


Actually you only need to execute:

sudo chmod +x ./gradlew

It works for me! And if it is too slow, you can execute:

./gradlew clean build

Why so many negative votes


I ran

sudo update-ca-certificates -f

to create a certificate file, and then:

sudo /var/lib/dpkg/info/ca-certificates-java.postinst configure`

and then change the command line of jar execution:

sudo java -cp xx.jar:lib/* co.com.ixxx.clixxxlarxa.Main

I ran

sudo update-ca-certificates -f

to create a certificate file, and then:

sudo /var/lib/dpkg/info/ca-certificates-java.postinst configure

I was back in business, thanks guys. It is a pity it's not included in the installation, but I got there in the end.


Some OpenJDK vendors releases caused this by having an empty cacerts file distributed with the binary. The bug is explained here: https://github.com/AdoptOpenJDK/openjdk-build/issues/555

You can copy to adoptOpenJdk8\jre\lib\security\cacerts the file from an old instalation like c:\Program Files\Java\jdk1.8.0_192\jre\lib\security\cacerts.

The AdoptOpenJDK buggy version is https://github.com/AdoptOpenJDK/openjdk8-releases/releases/download/jdk8u172-b11/OpenJDK8_x64_Win_jdk8u172-b11.zip


For me it got resolved just by upgrading a Jenkins plugin, "Email Extension Plugin", to the latest version (2.61).

These two plugins are responsible for email configuration in Jenkins:

  • Email Extension
  • Email Extension Template

For my case I didn't had specified VM Arguments fully.

(Run Configurations.. > (under Apache Tomcat) any server > (x)= Arguments > VM arguments:)

Make sure all VM Arguments are set tup correctly.


In my case the JKS file used in the client application was corrupted. I created a new one and imported the destination server SSL certificates in it. Then I used the new JKS file in the client application as a trust store, like:

System.setProperty("javax.net.ssl.trustStore",path_to_your_cacerts_file);

Source: Java SSL and certificate keystore

I use the (KeyStore Explorer) tool to create the new JKS. You can download it from this link, KeyStore Explorer.


For me it was caused by the lack of a trustedCertEntry in the truststore.

To test, use:

keytool -list -keystore keystore.jks

It gives me:

Keystore type: JKS
Keystore provider: SUN

Your keystore contains 1 entry

cert-alias, 31-Jul-2017, PrivateKeyEntry

Even though my PrivateKeyEntry contains a CA it needed to be imported separately:

keytool -import -alias root-ca1 -file rootca.crt -keystore keystore.jks

It imports the certificate, and then re-running keytool -list -keystore keystore.jks now gives:

Your keystore contains 2 entries

cert-alias, 31-Jul-2017, PrivateKeyEntry,
Certificate fingerprint (SHA1):
<fingerprint>
root-ca1, 04-Aug-2017, trustedCertEntry,
Certificate fingerprint (SHA1):
<fingerprint>

Now it has a trustedCertEntry, and Tomcat will start successfully.


Slim chance this will help anyone but....for anyone running Java 8 from a Docker Image on a Raspberry Pi (using AMD CPU) I got the following Dockerfile to build and run successfully for me

FROM hypriot/rpi-java
USER root

WORKDIR /usr/build/

RUN /usr/bin/printf '\xfe\xed\xfe\xed\x00\x00\x00\x02\x00\x00\x00\x00\xe2\x68\x6e\x45\xfb\x43\xdf\xa4\xd9\x92\xdd\x41\xce\xb6\xb2\x1c\x63\x30\xd7\x92' > /etc/ssl/certs/java/cacerts
RUN update-ca-certificates -f
RUN /var/lib/dpkg/info/ca-certificates-java.postinst configure

EXPOSE 8080

ARG JAR_FILE=target/app-0.0.1-SNAPSHOT.jar

ADD ${JAR_FILE} app.jar

ENTRYPOINT ["java", "-Djavax.net.ssl.trustStorePassword=changeit", "-Djavax.net.ssl.trustStore=/etc/ssl/certs/java/cacerts", "-jar", "app.jar"]

I expected things like this, being that I use an alternate JVM in my Talend Open Studio (support at the moment exists only until JDK 1.7). I use 8 for security purposes... anyway

  • Update your certificate store:

    sudo update-ca-certificates -f
    

then

  • add a new value in your initialization parameters

    sudo gedit $(path to your architecture specific ini i.e. TOS_DI...ini)
    
    Djavax.net.ssl.trustStore=/etc/ssl/certs/java/cacerts
    

For me, the second entry worked. I think, depending on the version of Talend Open Studio/TEnt + JVM, it has a different parameter name, but it looks for the same keystore file.


I had the same error, and the problem was not in configuring the JDK, but a simple wrong path to the JKS file in application.properties file under trust-store: parameter, double-check if the path is correct.
