Error description
ClassNotFound Exception while loading MBean proxy. The exception resolves itself as subsequent calls to the proxy are successful. Functionally this does not affect anything. The only issue is the existence of the ClassNotFoundException: com.ibm.ws390.management.proxy.EndpointMBeanProxy at java.lang.Class.forNameImple(Native Method) at java.lang.Class.forName(Class.java:136) at com.ibm.ws.management.descriptor.MBeanDescriptorLoader. setProxyOperationInfo(MBeanDescriptorLoader.java:1290)

Problem conclusion
The code is modified such that, if the collaborator class is not found in com.ibm.ws.runtime_6.1.0.jar, the class is loaded from the lib directory or from another bundle in the plugins directory. APAR PK02880 is currently targeted for inclusion in Service Level (Fix Pack) 7.0.0.8 of WebSphere Application Server V7.0. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
