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.
