VisualVM “not supported for this JVM” on all local applications?

Question

I have already spent a long time to load and test my application, now I need to profile it. But unluckily, the VisualVM always says \"not supported for this JVM\" on my loca

Answer 1

VisualVM needs to be run with the same JVM - at least Java 6 with the same 32-bit/64-bit size - as the program to be profiled. (You also need to be the same user, but then this message does not apply).

I would be triple-check that it was the exact same JVM in your situation.
