Hi,

Where can I find the source code in MAT that processes
HPROF_GC_CLASS_DUMP? I am trying to modify openjdk and dump additional
info from perm gen, so I want to make sure MAT can read the extra
info.

Looking at the vm source code
(http://hg.openjdk.java.net/jdk7/jdk7/hotspot/file/57552dca1708/src/share/vm/services/heapDumper.cpp#l215),
I can see two reserved fields in HPROF_GC_CLASS_DUMP and the plan is
to make use of them for extra info.

Thanks,
Tony
