NullPointerException in JAXBEncoderDecoder when marshalling a null Array
------------------------------------------------------------------------
Key: CXF-2329
URL: https://issues.apache.org/jira/browse/CXF-2329
Project: CXF
Issue Type: Bug
Components: JAXB Databinding
Affects Versions: 2.2.2
Reporter: Kaleb Walton
I have an Exception object that includes an array that is initialized to null.
When the JAXBEncoderDecoder is going to encode it, it encounters an NPE as
follows:
WARNING: Exception occurred while writing fault.

It seems like a simple null check could fix this one...
