[jboss-jira] [JBoss JIRA] Updated: (JGRP-928) Deadlock with concurrent stack in FC if RPC response blocks

Deadlock with concurrent stack in FC if RPC response blocks ----------------------------------------------------------- Key: JGRP-928 URL: https://jira.jboss.org/jira/browse/JGRP-928 Project: JGroups Issue Type: Bug Affects Versions: 2.6.8 Reporter: Brian Stansberry Assignee: Bela Ban Fix For: 2.6.9, 2.8 JGroups 2.4 and earlier had a deadlock problem in FC if a thread carrying an RPC came back down the stack with a response and blocked for credits. This was fixed with JGRP-465. But with the concurrent stack that fix has broken; needs to be reinstated. The variable that tracks upgoing threads needs to be converted from a ref to a Thread to a Set<Thread>.
