Description

I use jettison with jboss resteasy so I'm not a "real" jettison user.

I noticed that when I tried to unmarshall a String property like :
myText : null

My domain model object contains :
String myText = "null";

I tried to debug and found something strange :
at org.codehaus.jettison.mapped.MappedXMLStreamReader(MappedXMLStreamReader.java:152) :
currentValue is assigned with the toString() of newObj
but in case of

{myText : null}

newObj is JSonObject.NULL and JSonObject.NULL.toString() is "null"

Shouldn't this class handle a special case for JSonObject.NULL and assign null to currentValue?

This issue seems to be causing problems for the folks at CXF.
https://issues.apache.org/jira/browse/CXF-2916

While muddling through the code I actually found 2 cases where this special handling was required. Hopefully I got them all but I would be curious anyone finds any others.

Attached please find my patch.

JAXB will report an empty String. In order to get null, START/END element events may have to be skipped, possibly a configurable behavior
