[jboss-jira] [JBoss JIRA] Commented: (JBAS-7123) JBossCacheManager remains open to requests after shutdown

JBossCacheManager remains open to requests after shutdown --------------------------------------------------------- Key: JBAS-7123 URL: https://jira.jboss.org/jira/browse/JBAS-7123 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering, Web (Tomcat) service Affects Versions: JBossAS-5.1.0.GA Reporter: Brian Stansberry Assignee: Brian Stansberry Fix For: JBossAS-5.2.0.Beta1, JBossAS-6.0.0.Alpha1 The work Paul Ferraro did with LockValve ensures that typically application activity cannot reach the clustered session manager after its stop() processing executes, but testing is showing the StandardHostValve can end up causing calls to findSession that end up blowing up with an NPE. That's the specific issue; in general, the methods in the Manager API need to be hardened to react properly if invoked during/after shutdown. Solution is to use the same semaphore that LockValve uses, but use it internally -- add tryLock/release calls around the relevant code. Once stop() processing proceeds, tryLock will fail and the methods can react appropriately.
