Thread.sleep() is called with lock held in class NettyAcceptor -------------------------------------------------------------- Key: JBMESSAGING-1811 URL: https://jira.jboss.org/browse/JBMESSAGING-1811 Project: JBoss Messaging Issue Type: Bug Components: AS Integration Affects Versions: 2.0.0.beta4 Reporter: Wendy Feng NettyAcceptor has unefficient code as follow: public synchronized void pause() { ... try { Thread.sleep(500); } catch (Exception e) { } ... } Since the pause() method has been synchronized, calling Thread.sleep() can not realease the resource to other waiting threads. It may cause poor performance or even deadlock. -- 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
