[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2135) Deadlock occurs in Multithreaded Environment NamedEntryPoint lock and AbstractWorkingMemory actionQueue sync block.

[ https://jira.jboss.org/jira/browse/JBRULES-2135?page=com.atlassian.jira.p... ] Jonathon Leibundguth commented on JBRULES-2135: ----------------------------------------------- I believe something like this replaced method for AbstractWorkingMemory may resolve the issue, but I am not fully versed in the Drools Core code (pls don't kill me) - also this was a quick fix to unblock our project, there may be a more elegant impl., but point is to either move the execute() action outside of the sync block or find another avenue to resolve deadlock between actionQueue locking and NamedEntryPoint Reentrant lock: public void executeQueuedActions() { // fill this so that execute is called outside of the sync block to avoid deadlock Queue<WorkingMemoryAction> execQueue = new LinkedList<WorkingMemoryAction>(); synchronized ( this.actionQueue ) { if ( !this.actionQueue.isEmpty() && !evaluatingActionQueue ) { evaluatingActionQueue = true; WorkingMemoryAction action = null; while ( (action = actionQueue.poll()) != null ) { execQueue.add(action); } evaluatingActionQueue = false; } } WorkingMemoryAction execAction = null; while ( (execAction = execQueue.poll()) != null ) { try { execAction.execute( this ); } catch ( Exception e ) { if( e instanceof RuntimeDroolsException ) { // rethrow the exception throw ((RuntimeDroolsException)e); } else { System.err.println("************************************************"); System.err.println("Exception caught while executing action: "+execAction.toString()); e.printStackTrace(); } } } } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
