Local fix

• N/A
  

Problem summary

• When an object is JAXB marshalled its properties and those of
  its superclass(es) need to be marshalled.
  In the case that a property is overridden only one value needs
  to be marshalled.
  In constructing this table of properties and inherited
  properties the method ClassBeanInfoImpl.checkOverrideProperties
  checks for overridden properties in the subclass(es).
  This method did not check if the property array of the super
  class was null before attempting to iterate over it and hence
  threw the NullPointerException.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR13
  6.0.1 SR5
  .
   JVM has been updated to have a null check before iterating over
  the property array
  

Temporary fix
