I'm profiling a program with Visual VM. My program runs for a while and finally pops up a few plots using XChart showing the results. After the charts are displayed, I noticed in Visual VM some active threads "RMI TCP Accept", "Attach Listener", and "Signal Dispatcher". What are these threads? I assume they are there in connection with Visual VM only. Am I correct??

As you assume; Attach, Signal and RMI TCP Accept are for JMX monitoring by jConsole, VisualVM or similar.

The others are for garbage collection (e.g. Finalizer, Reference Handler).
