The server polling loop in RESTMBeanServerConnection.java catches IOExceptions and immediately retries the server poll. This makes sense for transient network issues. However, for an UknownHostException, the issue is unlikely to resolve quickly, and an immediate retry will likely cause an infinite loop, which will probably cause a leak of sockets

This affects all versions of Liberty prior to 25.0.0.1
