Category: JBossMQ Group: v3.2 Status: Open Resolution: None Priority: 5 Submitted By: Tim McCune (javajedi) Assigned to: Nobody/Anonymous (nobody) Summary: Multiple queue receivers can starve Initial Comment: In BasicQueue.java, receivers is a HashSet. The code iterates through this set to determine who to give the next message to. If there are multiple receivers listening to a single queue, most of the receivers will starve because the receiver who happens to have the lowest hashCode will keep jumping to the front of the iteration order. A simple fix of changing receivers from a HashSet to a LinkedList (1 line change) causes the receivers to get equal distribution of messages. I know this behavior is left up to the implementor in the JMS spec, but don't you think using a list makes much more sense? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=999660&group_id=22866 ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
