Hi All,

Request for review.

bugid: https://bugs.openjdk.java.net/browse/JDK-8164293

webrev: http://cr.openjdk.java.net/~jcm/8164293/webrev.00/

Desc: There were a few  memory leaks in  thread arena due to sweeper task.

Fix: Applied ResourceMark wherever applicable.

The slow growth of mtClass malloc(the one reported in bug) is not memory 
leak. It is application behavior in low codecache size setting( frequent 
sweeps), more InstanceKlass requires OopMapCache initialized here.

Best Regards,
