Decommision ends up calling MessagingService' shutdown() which closes the socket and then shuts down the executor. While that prevents new connections from being accepted after the shutdown, I don't see any attempt to prevent a recently created IncomingTcpConnection from trying to submit a callable to the already shut down deserialization executor. Perhaps a try/catch is in order that would log the incident with an explanation rather than cause exception leakage that gives the impression of something being wrong. Thoughts? -- / Peter Schuller
