First time connecting to a remote process is fine but then if you disconnect and reconnect it just hangs when you expect a breakpoint hit.
There no exceptions thrown and the you need to disconnect from the process in order for it to continue.
At first I thought this was an issue with JavaRebel but disabled first then removed the plugin and restated the application without it enabled.
