JMRI LCC Hub IOException

[dsand47]

When JMRI using the "CAN via GridConnect Network Interface" quits, the JMRI running the LCC Hub Server has an exception.

Both machines are running JMRI 5.5.4.

Client configuration (macOS 13.6):

Server status (Raspberry Pi OS 6.1.21):

Server log: session lcc hub.log

Quitting JMRI on the LCC Hub server creates similar errors on the client.

Is this perhaps just an issue of what's being logged?

The java.io.IOException is routine when a connection is broken from the remote end. Perhaps this should just be changed to a ERROR/WARN/INFO/DEBUG level (?) message without the traceback.
