Paul Ferraro created JGRP-1842: ---------------------------------- Summary: ForkChannel.getFORK(...) is not thread-safe Key: JGRP-1842 URL: https://issues.jboss.org/browse/JGRP-1842 Project: JGroups Issue Type: Bug Affects Versions: 3.4.4 Reporter: Paul Ferraro Assignee: Bela Ban If multiple concurrent threads attempt to create a ForkChannel using the same fork stack, and the flag is enabled that attempts to create the FORK protocol if missing - the FORK protocol can inadvertently insert multiple times. There needs to be some thread synchronization between the findProtocol(FORK.class) and protocol creation/insertion. -- This message was sent by Atlassian JIRA (v6.2.3#6260)
