Is there a way to use MAT to see what objects are in which generation? I'm trying to track down objects that should be short-lived and get collected as part of new generation collection that are making it to the old generation.
The hprof heap dumps do not contain any information about generations.
I asume that DTFJ dumps from IBM VMs may contain such information, however I don't know if there is a way to extract it. This could be a nice improvement to MAT. Can anyone with more knowledge in DTFJ help further?
