Category: JBossServer Group: v4.0 Status: Open Resolution: None Priority: 5 Submitted By: Scott M Stark (starksm) Assigned to: Nobody/Anonymous (nobody) Summary: Deadlock on shutdown with java5 testcase Initial Comment: There is a jboss-minimal-tests target in the testsuite ant16x-build.xml that starts the minimal config with the testsuite/output/lib/shutdown.sar deployed. This stops the server by undeploying the shutdown.sar. The ExitOnShutdown in this sar calls System.exit in its stop method and under java5 this is causing a deadlock because the javax.management.NotificationBroadcasterSupport.sendNotification method happens to be synchronized in the java5 implementation while it is not in the jboss implementation. See the attached thread dump. ---------------------------------------------------------------------- >Comment By: Adrian Brock (ejort) Date: 2004-10-21 01:21 Message: Logged In: YES user_id=9459 The fix would appear to be not to synchronize on "this" or have NO synchronized methods on anything that extends NotificationBroadcasterSupport. I see nothing in the javadoc that suggests this leak of a synchronization to subclasses. It should be an internal synchronization. I will forward this to the JMX 2.0 spec commitee. But this probably needs reporting as a bug to Sun. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=1051174&group_id=22866 ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
