Frequent Java runtime crashes when compiling GWT code

We are seeing frequent Java runtime crashes (and I *really* mean often: about 2 in 3 compilations crash) while building our GWT-based application.

I haven't been able to figure out, precisely *what* is triggering this (see the log-snippet below). It happens more or less right at the beginning of that goal and from what I read there it seems to be in the Maven plugin that jars up our module with the GWT stuff in it.

Are others seeing this or similar Java runtime crashes as well? I recently upgraded the JDK that our CI-environment is using (we are bound to Java-8 for the time being) hoping this would improve the situation, but its still the same and it getting mighty tedious!

Any ideas or suggestions?

Just in case: it's NOT a HW-issue! The build environment is running in an OpenShift-based virtual environment and these crashes happen for *this* project only. We have other GWT-based applications and these build fine in the same environment. I have seen similar crashes before (but really *very* seldom only). But with *this* projects it's getting out-of-hand lately.

Can you try testing with adoptopenjdk?

I've had issues with stock openjdk before with odd crashes that don't happen with adoptopenjdk.

*ouch*

I'm not sure where to proceed from here without being able to recreate the issue.
