[esb-issues] [JBoss JIRA] Created: (JBESB-3397) halt()/dispose() race condition in DroolsRuleBaseState

halt()/dispose() race condition in DroolsRuleBaseState ------------------------------------------------------ Key: JBESB-3397 URL: https://jira.jboss.org/browse/JBESB-3397 Project: JBoss ESB Issue Type: Bug Security Level: Public (Everyone can see) Components: Content Based Routing Reporter: David Ward Assignee: David Ward Fix For: 4.9 What happens: Thread 1 creates a stateful session and spawns daemon Thread 2 (with the correct TCCL). Thread 2 calls fireUntilHalt() on the stateful session, which suspends that Thread. Thread 3 calls halt() on the stateful session, which will cause Thread 2 to stop *once all the rules have finished firing*, however returns immediately. Thread 3 calls dispose() on the stateful session, *but the rules might not have finished firing*. This could cause unpredictable results. What needs to happen: Thread 1 creates a stateful session and spawns daemon Thread 2 (with the correct TCCL). Thread 2 calls fireUntilHalt() on the stateful session, which suspends that Thread. Thread 3 calls halt() on the stateful session, which will cause Thread 2 to stop once all the rules have finished firing, however returns immediately. Thread 3 calls join() on Thread 2, which will return *once all the rules have finished firing* and Thread 2 is done. Thread 3 calls dispose() on the stateful session safely, as now the rules have finished firing. This means predictable results. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
