>Problem: In some managed WebLogic use cases (SOA) the a JMX spec factory call returns MBeanServer instances in a different order. It turns out that the strategy of using the first one with a non-null domain does not work in the SOA case for WebLogic - as it does for JBoss. MBeanServer mBeanServerRuntime = (MBeanServer) MBeanServerFactory.findMBeanServer(null).get(0); The fix could be on the SOA side to check both MBeanServer instances, or in EclipseLink using a change to our WLS platform class (extra registration checking, or revert to WLS specific ExecuteThread lookup). Either way, the new generic registration code is out - only for WebLogic, but stays for WebSphere, JBoss and Glassfish. We need to either check that the correct [0] or [1] indexed MBeanServer is being used (by looking for WebLogic MBeans), or - simpler, just use the old proprietary ExecuteThread (non-JMX spec) MBeanServerFactory code. This is a rework of design issues 3 and 4 of bug # 316513 In 316513 design issue #3 and #4 a decision was made to use the first one on the list that has a non-null domain. However, the indexing code can be changed to check the classLoader in this instance. Or we may need to use one of the other 2 methods to get the correct server directly instead of receiving a List of them from the JMX spec function. This looks to be related to the fact that 2 MBeanServers are available from the MBeanServer factory when running either WebLogic on JRockit.

>A full fix will either revert the weblogic part of 7844 or refactor to use the "com.bea" containing server In the interest of expediency - a quick fix will be to revert to pre 7844 code - just for WebLogic. - this will gaurantee that we only get the single "com.bea" based server for registration. We can revisit whether we want to add logic to determine which instance to use when multiple MBeanServers are returned in "some" managed server cases. >Attachment #174515 [details]: Handle multiple MBeanServer instances from MBeanServerFactory for bug #316513 >revert line 51 of https://bugs.eclipse.org/bugs/attachment.cgi?id=173104&action=diff#foundation/org.eclipse.persistence.core/src/org/eclipse/persistence/platform/server/JMXServerPlatformBase.java_sec1 mBeanServer = (MBeanServer) MBeanServerFactory.findMBeanServer(null).get(0); line 109 (rev 7777) of https://bugs.eclipse.org/bugs/attachment.cgi?id=173897&action=diff#foundation/org.eclipse.persistence.core/src/org/eclipse/persistence/platform/server/JMXServerPlatformBase.java_sec1 if(mBeanServerList.size() > 1) { http://fisheye2.atlassian.com/changelog/eclipselink/?cs=7777 and https://bugs.eclipse.org/bugs/attachment.cgi?id=174515&action=diff http://fisheye2.atlassian.com/changelog/eclipselink/?cs=7844
