sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run()

What is it and why is it taking up so much processing time?

I’m not very familiar with it but I know the rmi package contains “Remote Mud Interfaces” which have to do with MUDs (Multi User Dungeons/Displays) which = online game/application.

Your program is having an issue getting data from the network. A quick google search can help:

That’s what I thought, problem is I don’t have online functionality, maybe it has something to do with visualvm connecting to my application
