java.lang.OutOfMemoryError: PermGen space

I am on the latest Fedora distro, running Intellij Ultimate. I have also configured Maven Runnger VM Options as -Xmx4g -XX:MaxPermSize=4g

How could I debug why the VM Options are not getting applied to the test or why the tests even dont run with default options. Same project works perfectly fine on another machine running Ubuntu Trusty.

Does this occur when running tests in IDEA directly or also when running mvn test from the command line? — Freiheit

You can apply a process of elimination to find out which argument is causing trouble. I suspect in this case it's either the MaxPermSize flag being equal to Xmx, or the Xmx value being set to 4gb (if the system in question is a 32-bit architecture).

Try modifying the flags (of course make a backup!) to test those hypothesis and iterate from there.

Installing https://copr.fedorainfracloud.org/coprs/jschwart/openjdk-7/ fixed the issue. Binaries are here https://schwart6.home.xs4all.nl/fedora25/binaries/
