Class JavaLaunchHelper is implemented in both … libinstrument.dylib. One of the two will be used. Which one is undefined

Question

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?

Answer 1

For JetBrains IntelliJ IDEA: Operate to Help -> Edit Custom Properties... Generate the file if it requires you to build it. To impair the wrong message paste the following to the file you generated:

idea_rt
idea.no.launcher=true

This will bring an impact on the restart of the IntelliJ.
