Review Request (s) - 7015169 GC Cause not always set

[Bengt Rutisson]

Hi Everybody,

Following up on a mail discussion called "jstat LGCC column shows" on 
this mailing list. Yasumasa Suenaga has agreed to contribute the patch 
that he made to the OpenJDK project. I am helping him to get it pushed 
into the OpenJDK repositories.

We created bug 7015169 for this issue. It is not available on 
http://bugs.sun.com yet, but I hope it gets published there soon.

To push we need a couple of reviews. Here is the webrev:
http://cr.openjdk.java.net/~brutisso/7015169/webrev.00/

The problem was that _gc_cause was not set by all VM_GC_Operation that 
can request a GC. This was visible through jstat and with Yasumasa's fix 
the LGCC columns shows the correct GC cause.

Thanks,
Bengt
