This is a problem because some jars are not being recognized because they only have a META-INF/MANIFEST entry (no META-INF dir entry) and are not being added to the deployment classpath because the JarStructure test for a META-INF entry is failing. The jbossws.sar/wsdl4j.jar is another example that causes this NCDFE: Caused by: java.lang.NoClassDefFoundError: javax/wsdl/WSDLException at jrockit.reflect.InitialConstructorInvoker.newInstance([Ljava.lang.Object;)Ljava.lang.Object;(Unknown Source) at java.lang.reflect.Constructor.newInstance([Ljava.lang.Object;J)Ljava.lang.Object;(Unknown Source) at org.jboss.mx.server.MBeanServerImpl.instantiate(MBeanServerImpl.java:1242) at org.jboss.mx.server.MBeanServerImpl.instantiate(MBeanServerImpl.java:286) at org.jboss.mx.server.MBeanServerImpl.createMBean(MBeanServerImpl.java:3 Looks like some synthentic parent entries will be needed.
