Could I have a couple of reviews for this change?
Before the changes to use the unified logging framework for the GC
logging the number of GC worker threads was logged for each G1
evacuation pause. It was printed as part of the "Parallel Time" line:
[Parallel Time: 5,5 ms, GC Workers: 23]
This information was lost in the conversion to the unified logging
framework. This is relevant information and should be added back.
The proposed patch adds this back as a separate log line. That looks
[1,647s][info][gc,task ] GC(36) GC Workers: 23
The logging is done in AbstractWorkGang which is shared between G1 and
CMS (ParNew). So, this information is now also logged for CMS.
