      Description

      BaseServer.getConnection creates a socket and puts it in the shared map under a lock.

      However it does not connect the socket inside the lock, so another thread calling getConnection at the same time can get the unconnected socket, which will throw a NPE when used because it's not connected yet (all the checks before returning and using it only look for isOpen, not isConnected).

      java.lang.NullPointerException
