You could try a tool called PerfAnal, http://developer.java.sun.com/developer/technicalArticles/Programming/perfanal/index.html

Not that this will help you at all but the reason I think HAT wont work is just soo small and insignificant and annoying that everyone should know. I stress the "I think" above again; If you look at heap dumps from 1.3 and say 1.2, you will see that the ROOT statements contain less information now, info. that Im guessing HAT is looking for. Took me days to figure that out! I suppose using an old version of Java just for this purpose is out of the question?
