Hi Everyone,
Can I please have a couple of volunteers look over the fix for this CR -
the webrev can be found at:
http://cr.openjdk.java.net/~johnc/8005875/webrev.0/
Summary:
One of the modules in the Kitchensink test generates a VM_PrintThreads
vm operation. The JVM crashes when it tries to print out G1's concurrent
marking worker threads when ParallelGCThreads=0 because the work gang
has not been created. The fix is to add the same check that's used
elsewhere in G1's concurrent marking.
Testing:
Kitchensink with ParallelGCThreads=0
Thanks,
JohnC
