Description string

The example stack trace shows that the application has caught a CORBA org.omg.CORBA.MARSHAL system exception. After the MARSHAL exception, some extra information is provided in the form of a string. This string should specify minor code, completion status, and other information that is related to the problem. Because CORBA system exceptions are alarm bells for an unusual condition, they also hide inside what the real exception was.

Usually, the type of the exception is written in the message string of the CORBA exception. The trace shows that the application was reading a value (read_value()) when an IllegalAccessException occurred that was associated to class com.ibm.ws.pmi.server.DataDescriptor. This information is an indication of the real problem and should be investigated first.
