This class was used for execution trace analysis. Not related to this work.
I'll remove it (but save it in some place before)

Here is the work related to GC profiling (used for the IWST paper).
How to use it?
scavenge.log(but it has info about the FullGCs also) will be generated in the current directoryWIP
Still need some work to be integrated.
I also want to be sure that performance is not affected (significantly) if the profiler is off.
