Subject [jira] Created: (CXF-1602) DataTypeAdapter causes NPE with jaxb-impl 2.1.6 if multiple bindings go to the same java type

DataTypeAdapter causes NPE with jaxb-impl 2.1.6 if multiple bindings go to the same java type
---------------------------------------------------------------------------------------------

                 Key: CXF-1602
                 URL: https://issues.apache.org/jira/browse/CXF-1602
             Project: CXF
          Issue Type: Bug
            Reporter: aaron pieper


A NullPointerException occurs in the attached example. I'm not sure exactly what causes it,
but the following conditions seem to play a role:

  * jaxb-impl v2.1.6. If we switch to jaxb-impl v2.0.1, the NPE doesn't happen.
  * We define a custom binding.xml with two classes mapped to the same java type. In this
example, "date" and "datetime" are both mapped to "java.util.Date". If we remove the "datetime"
binding, the NPE doesn't happen.

The result is that it tries to pass a "null" value into the Date->String adapter, which
causes an NPE.

Caused by: java.lang.NullPointerException
