Hi Francis,
Did you have a specific reason to get the heap dump using code? You should be able to acquire a Heap dump (hprof) from within MAT using File > Acquire heap dump. VisualVm also can do that I believe (right-click on process?). There is also the jmap command
that can output a heap dump. Just to save you some time for next time ;)

It appears that TmfExperiment is not AutoClosable as other traces, and calling dispose() method on the experiment solved the issue.

For the debugging, I needed the HeapDump class. However, I could not find it in other linuxtools plug-ins, and I don't know how to search for that class in p2 repo, such as Orbit. I think that would be very helpful to have it in the class path. Here is
the slightly modified version I have:
