[jboss-jira] [JBoss JIRA] Commented: (JBAS-5615) Synchronization mutex for clustered environments

Synchronization mutex for clustered environments ------------------------------------------------ Key: JBAS-5615 URL: https://jira.jboss.org/jira/browse/JBAS-5615 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: JBossAS-4.2.2.GA Reporter: Nick Belaevski Assignee: Scott Marlow Priority: Minor Quote from http://www.jboss.com/index.html?module=bb&op=viewtopic&t=136590 : "they'll need to be thread safe or have access to them synchronized". There's no object to synchronize against: SessionBasedClusteredSession doesn synchronization against itself: public void writeExternal(ObjectOutput out) throws IOException { synchronized (this) { ... } } but application developers see the wrapped one (instance of StandardSessionFacade), so synchronizing against session object does not prevent from concurrency errors
