I just got a frontend compiler bug in Intellj (when trying to run my code). This used to work w/o problems until a few moments ago. "Invalidate cache and restart" did not help. IntellJ uses 720 of 1950MB right now.

I already have 2GB configured and IntellJ says that it currently only uses 750MB

[Jakub Pi]

Maybe fragmentation? If it can't find enough contiguous space for a large allocation, it could still happen.

If you build with IDEA, try changing "Build process heap size" setting in Settings | Build, Execution, Deployment | Compiler

[nkiesel]

yes, building with IDEA. I just doubled the "build process heap size" to 1400 but that did not make a difference
