open -PID- does not return

Thanks for this great tool, I use it a lot. But in one of my environments, I am unable to open a connection to a running Tomcat (all components do work on other machines with JMXTerm uber 1.0.2). Please refer this attempt:

after both open commands in my screenshot I've waited several minutes without it getting back to prompt. I then ctrl+c out of it. I dont understand, what I am missing here. There is no feedback (also with verbose option on). I'd expect an error, or a timeout oslt. I'd be happy if you could advise!

Is 3333 the tomcat HTTP port or JMX remote port?

If you haven't seen it, this is JMX remote port. https://docs.oracle.com/javadb/10.10.1.2/adminguide/radminjmxenablenoauth.html
