RFR(xs): 8213834: JVMTI ResourceExhausted should not be posted in CompilerThread

[Thomas Stüfe]

Dear all,

may I please have reviews on this small patch. Note that this is
borderline serviceability. I try to avoid crossposting, but if you
think this should be looked at by serviceability feel free to forward
it there.

Issue: https://bugs.openjdk.java.net/browse/JDK-8213834

CR: http://cr.openjdk.java.net/~stuefe/webrevs/8213834-jvmti-reourceexhausted-shall-not-be-posted-from-compiler-thread/webrev.00/webrev/

Short description: we may post ResourceExhausted from Compiler
threads. Handlers of this event may call back into the JVM, which may
cause problems since we run in the compiler thread. The proposed
solution is not to post the event in that case.

See previous discussion here:

Thanks, Thomas
