Error - trustAnchors parameter must be non-empty

Question

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

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

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

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

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

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    lt fingerprint gt  root-ca1  04-Aug-2017  trustedCertEntry  Certificate fingerprint  SHA1    lt fingerprint gt    Now it has a trustedCertEntry  and Tomcat will start successfully
