Hmm this is pretty hard to do right now.  The best way to test this is
to try to bind to the port with a little connection test.

BTW I'm presuming that the two installations are running in separate
JVMs.  Am I correct here or did I miss something?

Sounds like you want to test if the server has bound in the same JVM
instance.  Is this the case?

Yeah it might for sure.   I do want to understand your use case a bit
better.   Could you elaborate some more with greater detail?
