Looks good in general, but I would prefer a more descriptive name than 
_regions in G1HeapSummary, something like _numberOfRegions and then 
maybe have that propagated into the trace.xml as well. The label already 
have this info, but I would be nice if it was reflected in the code as well.

Thanks,
Stefan
