Class JavaLaunchHelper is implemented in both .../java and .../libinstrument.dylib

[stig]

When adding the quasar-core Java agent to my project.clj I get this warning when running Leiningen:

% lein repl
objc[4600]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

This is my project.clj:

It seems to be an annoyance related to a JDK issue that not been fixed yet for 1.8: http://stackoverflow.com/questions/18794573/objc10012-class-javalaunchhelper-is-implemented-in-both-libinstrument-dyl

I'll close it as there's not much that can be done in Quasar/Pulsar.

You must go to Preferences/Build, Execution, Deployment/Debugger and disable the option: "Force Classic VM for JDK 1.3.x and earlier" This works for me

Proposed solution didn't work for me, still have "...One of the two will be used. Which one is undefined."

Same for me as well, the solution is not working.
Jdk version: jdk1.8.0_131.jdk
Tried running both on Intellij Idea and Eclipse.
Eclipse is not even showing error and closes the execution without any error.

I hit the same error - none of the proposed solutions works for me

Disabling "Force Classic VM for JDK 1.3.x and earlier" works fine as @davoVloom described, but only after restart the IDE

@vryba It just works in Debug Mode, but in Run Mode it won't in IntelliJ !
