[jboss-jira] [JBoss JIRA] Updated: (JBAS-4314) A deadlock condition in DistributedReplicantManagerImpl

A deadlock condition in DistributedReplicantManagerImpl ------------------------------------------------------- Key: JBAS-4314 URL: http://jira.jboss.com/jira/browse/JBAS-4314 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering Affects Versions: JBossAS-4.0.2 Final Environment: Linux 2.6.x, Sun-JVM 1.5.0_11-b03, 1.6.0-b105, JBoss 4.0.2.final. Reporter: Bernd Köcke Assigned To: Brian Stansberry Attachments: DistributedReplicantManagerImpl.java.patch While working on JBAS-4313 I found a deadlock condition in DistributedReplicantManagerImpl. All methods are using the lock order localReplicants -> replicants. But method purgeDeadMembers uses replicants -> localReplicants. To solve the problem I moved the notifyKeyListeners out of the synchronized(replicants)-block. Newer versions of JBoss are using maps from the concurrent-package and not the normal java.util.HashMap. Maybe this solves the problem, too.
