             Summary: UDP: remove invocation of DatagramSocket.isClosed()
                 Key: JGRP-1780
                 URL: https://issues.jboss.org/browse/JGRP-1780
             Project: JGroups
          Issue Type: Enhancement
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 3.5


In UDP, we check whether a datagram socket is closed by invoking {{DatagramSocket.isClosed()}} for every message that's sent. Flight recorder showed that this creates a bit of lock contention as isClosed() is synchronized.
SOLUTION:
* Simply remove the check. If a socket is closed we'll catch the exception anyway and handle it.
