[linuxtools-dev] Memory usage of TmfExperiment

[Francis Giraldeau <francis.giraldeau@xxxxxxxxx>]

I used Eclipse Memory Analyzer (MAT) to find the object holding a reference to a large temporary chunk of memory. It appears that TmfExperiment is not AutoClosable as other traces, and calling dispose() method on the experiment solved the issue. (Whole story: http://multivax.blogspot.ca/2014/08/pinpoint-memory-usage-of-java-program.html )

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:
