> The following changes will be made:
> 1) JAXB Pooling Optimization
>    JAXBContext objects are now pooled in a WeakHashMap.  
> 2) JAXB Advanced Pooling Optimization:
>    Added code to pool JAXB Unmarshaller, Marshaller, and JAXBIntrospector.  Pooling is
initially
>    disabled for these objects until we get more information from the IBM performance
team.
>    To enable the pooling, set JAXBUtils.ENABLE_ADV_POOLING=true
> 3) MTOM Travesal Optimization
>    Changed the MTOM traversal code to use the more performant OMNavigator utility. 
> 4) XMLInputFactory/XMLOutputFactory Pooling Optimization:
>    Refactored this code to use OM StAXUtils. OM StAXUtils contains code to pool these
objects. 
> 5) XMLStreamReader/XMLStreamWriter closing:
>    Scrubbed jaxws component and added close() calls where appropriate.
> 6) Servicability:
>    * Additional servicability is added to identify why a message is consumed.
>      The "Message is already consumed" error is changed to advise the user to run with

>      debug.  Running with debug will highlight the place in the code where the message
is 
>      first consumed...which will greatly aid in error detection.
>    * Added more trace
