Issue: Once connected to application, the option for perform GC is enabled button. However the heap dump button is greyed out. Also in the "application" menu its greyed out. Does it work for apps connected via jmx locally?

Description: Connecting via jmx to a websphere application. Stats and data come back but I want to see what's in memory for objects to look at a class object size. Heap dump button is greyed out.

Version: VisualVM 2.0.4
