[jboss-jira] [JBoss JIRA] Created: (JBCACHE-1025) JBossCache mbean registration fails on WebSphere 6.1

JBossCache mbean registration fails on WebSphere 6.1 ---------------------------------------------------- Key: JBCACHE-1025 URL: http://jira.jboss.com/jira/browse/JBCACHE-1025 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 1.4.1.SP3, 1.4.1.SP2, 1.4.1.SP1 Environment: WebSphere 6.1 Reporter: Jerry Gauthier Assigned To: Jerry Gauthier Fix For: 1.4.1.SP4 At least two customers have encountered the following problem when starting JBossCache on WebSphere 6.1. When the cache is started and the cache's interceptor mbeans are registered, the registration fails with an InstanceAlreadyExistsException. This occurs even on initial startup and despite the fact that JBossCache only registers a name if it's not already registered. A post to the ActiveMQ Forum at http://issues.apache.org/activemq/browse/SM-883 suggest that this problem occurs because WebSphere modifies the mbean's registration name during the registration process. Subsequent tests to determine if the mbean has been registered apparently fail unless the client uses the name generated by WebSphere. (This is unverified but seems plausible.)
