Project: JiBX
Issue Type: Bug
Components: BindGen, maven plugin
Affects Versions: JiBX 1.2.3
Reporter: Oliver Siegmar
This is my binding file:
{code}
<binding direction="output">

<value name="CheckResultType" get-method="getCheckResultType"/>
</mapping>
</binding>

Calling "mvn package" results in this Exception:

The class {{my.package.CheckResult}} is rather an interface, which causes this
NPE. If I convert the interface to a class, no Exception is thrown.
