PH34951: NullPointerException error may occur with Axis2 marshaller.

APAR status

• Closed as program error.

Error description

• A NullPointerException may be thrown for a class lookup out of
  org.apache.axis2.jaxws.marshaller.impl.alt.MethodMarshallerUtils
  when using a custom web service fault which is or
  references inner classes. The top of the root cause exception
  will look like this:
  
  java.lang.NullPointerException

  java.lang.Class.forNameImpl(Native Method)
  at
  java.lang.Class.forName(Class.java:407)

Local fix

• Remove the nested classes from the fault class if possible.
