[jbosstools-issues] [JBoss JIRA] (JBIDE-17656) Forge crashed Eclipse

Vineet Reynolds commented on JBIDE-17656:
-----------------------------------------

An update: I did manage to reproduce this once using Antonio's script. The hs_err_pid dump produced wasn't informative, except indicating that the JVM crashed.

I updated the JDK later to Oracle Java 8 update 20, and the crash seems to have disappeared. JVM runtime analysis however gives a hint as to why the crash might have occurred - GC activity is rather high (as low as 30% and even higher during scaffolding, only in Windows). I suspect a OS-contextual {{System.gc}} invocation is responsible for this. We should/must throttle this.
