After upgrade to IDEA 2017.1, Class JavaLaunchHelper Error
Answered
I just updated to IntelliJ IDEA 2017.1 and now I get this error message every time on runtime:
objc[3318]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/bin/java (0x107a4c4c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x107b144e0). One of the two will be used. Which one is undefined.
Everything works as usual. It's just really annoying to look at. I didn't have this error message before in the older version of IntelliJ.
If there is no fix is it then possible to just tell IntelliJ to not give me this specific error when I run my programs?

It's a long standing Java bug: http://stackoverflow.com/questions/20794751/class-javalaunchhelper-is-implemented-in-both-one-of-the-two-will-be-used-whic.
But, IntelliJ IDEA 2016.3 didn't have this error message with same JDK version. Really java bug??
Please follow https://youtrack.jetbrains.com/issue/IDEA-170117 for updates. We'll investigate why it happened after the update.
I have same error on MaсOS 10.12.3, IDEA Community Version 2017.1.
Please check if 8u152 Build b01 from https://jdk8.java.net/download.html fixes the problem.
8u152 has "early access" status. And 2016.3 didn't have this problem.
