Local fix
Problem summary
When the class specified in the javax.management.builder.initial system property cannot be found, the JMX MBean server fails to start. Before Java 8.0.5.0, and in other Java implementations, when the javax.management.builder.initial class is not found, then a javax.management.JMRuntimeException is thrown, which can be caught and handled gracefully. The issue fixed here is that after Java 8.0.5.0, the IBM SDK for Java throws an ExceptionInInitializerError, which is not handled in the same way, causing an application error.
Problem conclusion
The Java SDK has been updated to throw an exception that can be handled as before, rather than an ExceptionInInitializerError. . This APAR will be fixed in the following Java Releases: 8 SR5 FP41 (8.0.5.41) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
