Hi all,

Please review this patch to make sure that the "heap summary after gc" 
events  are only sent once.


This was found in one of our closed JFR tests. From the bug report:
For client VM and G1 GC several vm/gc/heap/summary events with property 
when='After GC' could be emitted for the same GC ID.
At the same time there will be only one 'Before GC' vm/gc/heap/summary 
event for the same GC ID.
