Thread creation during deactivate_object ---------------------------------------- Key: JBAS-1182 URL: https://jira.jboss.org/jira/browse/JBAS-1182 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: IIOP service Reporter: SourceForge User Assignee: Stefan Guilhen SourceForge Submitter: kevinconner . This is a duplicate of bug 527 in the JacORB database. It is being submitted here so that a patch may be applied to the JBoss patched version of JacORB. http://www.jacorb.org/cgi-bin/bugzilla/show_bug.cgi?id=527 The deactiviation of an object causes Thread creation in AOM.remove. Would it be possible to use a thread pool instead of creating new threads? A possible solution could be to have the RequestController provide a notification mechanism (instead of a thread waiting on object completion) and have the notification request work from the thread pool. The attached patch uses a threadpool to prevent the thread creation but I don't believe it is the best solution.
