This is probably too late, but I had the same problem, and setting a breakpoint and then starting in debugging mode didn't help at all. I eventually found out that VisualVM saves its temporary data in the folder %TMP%/hsperfdata_[username], on my Windows machine that folder was C:\Users\Jacob\AppData\Local\Temp\hsperfdata_Jacob for instance.
