Dear @kstefanj,
I have made a new commit that refined the HeapBlockClaimer. Thanks a lot
for your review!
And I have conduced the following tests: (on x86_64 ubuntu system)
* tier1 test with no regression
* jmap -histo:parallel=[N] [pid] with N = 0,1,2,3,4, 10000, with a java
thread running with "-XX:+UseParallelGC -XX:ParaelGCThreads=4" options. All
test worked as expected (All test worked normally and "histo" data dumped are
same)
Thanks,
Lin
