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

Daniel Kulp resolved CXF-1602.
------------------------------

       Resolution: Fixed
    Fix Version/s: 2.0.7
                   2.1.1
         Assignee: Daniel Kulp


First, there is a problem with the sample:
In the binding.xml, you map both xsd:date and xsd:dateTime to parseDateTime.   xsd:date should be mapped to just parseDate.


The bug is for "optional" stuff (like the optional date), the null is passed into the parseDateTime/printDateTime routines.   We need to just return null there as well.

> 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.
