Hi Dingwen.
Our tool 'MemTrace', which is available as a patch in the research
archive at:
http://sourceforge.net/tracker/?func=detail&aid=2741045&group_id=128805&atid=723235will give you lifetime profiles, though it does so by performing
regular full-heap GC's using a semispace collector, which I guess is
not what you want. However, it might be possible to modify it to
perform non-moving collections if you are unable to find any other
mechanism to use.
Cheers,
Chris.
