Hi all,

I discussed about FullGC counter for Concurrent GC:
    http://mail.openjdk.java.net/pipermail/hotspot-gc-dev/2016-March/016774.html

I found same issue on JBS:
    JDK-6291341: jstat: FGC counter confusing when CMS GC is used

JDK-6291341 was closed with Cannot Reproduce.
However, I showed cause of this issue in above thread.

I uploaded patches for this issue:

    hotspot: http://cr.openjdk.java.net/~ysuenaga/JDK-6291341/poc/hotspot/
        jdk: http://cr.openjdk.java.net/~ysuenaga/JDK-6291341/poc/jdk/

JDK webrev includes testcase update.
All tests for jstat work fine.


Should I work for it as new issue? Or should I reopen JDK-6291341?

I cannot access JPRT.
So I need a sponsor.


Thanks,

Yasumasa
