I upgraded to the latest Java 7u40 on MacOS X and started getting the following message on the console when launching my application using Eclipse. The app works fine but I would like to find out the cause of the problem and hopefully a fix for it.
objc[10012]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.
Does anyone know why this message is printed and how to fix it?

To solve this issue, I downgraded to JDK version 1.7.0_21. then I used this little bash script to change the version I use.
function setjdk() {
if [ $# -ne 0 ]; then
removeFromPath '/System/Library/Frameworks/JavaVM.framework/Home/bin'
if [ -n "${JAVA_HOME+x}" ]; then
removeFromPath $JAVA_HOME
fi
export JAVA_HOME=`/usr/libexec/java_home -v $@`
export PATH=$JAVA_HOME/bin:$PATH
fi
}
function removeFromPath() {
export PATH=$(echo $PATH | sed -E -e "s;:$1;;" -e "s;$1:?;;")
}
Once you have the bash script in your zshrc/bshrc file, just call setJdk 1.7.0_21
and you're good to go.

From what I've found online, this is a bug introduced in JDK 1.7.0_45. I've read it will be fixed in the next release of Java, but it's not out yet. Supposedly, it was fixed in 1.7.0_60b01, but I can't find where to download it and 1.7.0_60b02 re-introduces the bug.
I managed to get around the problem by reverting back to JDK 1.7.0_25. Probably not the solution you wanted, but it's the only way I've been able to get it working. Don't forget add JDK 1.7.0_25 in Eclipse after installing the JDK.
Please DO NOT REPLY directly to this email but go to StackOverflow: Class JavaLaunchHelper is implemented in both. One of the two will be used. Which one is undefined
As other answers detail, this is a bug in the JDK (up to u45) which will be fixed in JDK7u60 - while this is not out yet, you may download the b01 from: https://jdk7.java.net/download.html
It's beta, but fixed that issue for me.
If you're using IntelliJ & Mac just go to Project structure -> SDK and make sure that there is Java listed but it points to sth like
/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
Rather than user home...

Works also for Java 1.8:
# in ~/.zshrc and ~/.bashrc
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_92.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH
This fixed my issue on java 8.
jdk-7u80-macosx-x64.dmg fix this problem.
As of October 2017, this issue is now resolved in
Not sure if this is the cause of the problem, but I got this issue only after installing JVM Monitor.
Uninstalling JVM Monitor solved the issue for me.
OSX Mojave 10.14.5 (18F132) IntelliJ 2019-1 Community Edition. It worked setting idea.properties file. I also configured JAVA_HOME pointing to /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/
idea_rt idea.no.launcher=true
?? For JetBrains IntelliJ IDEA: Go to Help -> Edit Custom Properties...
. Create the file if it asks you to create it. To disable the error message paste the following to the file you created:
idea_rt
idea.no.launcher=true
This will take effect on the restart of the IntelliJ.
Well, after some struggling, what worked for me was completely removing the current JDK, as described here:
sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk
sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane
sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -rf /Library/LaunchAgents/com.oracle.java.Java-Updater.plist
sudo rm -rf /Library/PrivilegedHelperTools/com.oracle.java.JavaUpdateHelper
sudo rm -rf /Library/LaunchDaemons/com.oracle.java.JavaUpdateHelper.plist
sudo rm -rf /Library/Preferences/com.oracle.java.Helper-Tool.plist
Then installed 1.7.0_21, which was downloaded from here.
Now java -version
prompts:
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b12)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)
Install Java 7u21 from: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html#jdk-7u21-oth-JPR
Set these variables:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH
Run your app and have fun :)
