the number of messages
Total time for which application threads were stopped: X.Y seconds
produced by PrintGCApplicationStoppedTime increased a lot between Java 5
and 6. All of the additional messages refer to extremely short pause
times, and none of the prints anything when adding PrintHeadAtGC, so it
looks like they are not directly related to actually running a GC task.
Can someone give an indication, what other typical reasons for those
pauses exist? I tried to track it back from vm/runtime/vmThread.cpp, but
wasn't really successful.
