[jboss-jira] [JBoss JIRA] Closed: (JBAS-6487) org.jboss.mq.server.MessageReference does override equals, but not hashCode

org.jboss.mq.server.MessageReference does override equals, but not hashCode --------------------------------------------------------------------------- Key: JBAS-6487 URL: https://jira.jboss.org/jira/browse/JBAS-6487 Project: JBoss Application Server Issue Type: Quality Risk Security Level: Public(Everyone can see) Components: JMS (JBossMQ) Affects Versions: JBossAS-4.2.3.GA Reporter: Rico Neubauer Assignee: Adrian Brock Fix For: JBossAS-4.2.4.GA Attachments: JBAS-6487.diff org.jboss.mq.server.MessageReference does override equals() (and even compareTo()), but not hashCode(). This is a potential issue, when adding MessageReferences to hashCode-based Collections such as Hashmap or HashSet. from java.lang.Object: If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result. Will append a patch. Came across this when searching for the root of a symptom, where messages were processed and removed from the MessageCache, but still were persistent in database - don't know yet if it's related.
