Scott M Stark resolved JBMAN-42.
--------------------------------

    Resolution: Done


There is a DefaultMetaValueFactory.mapNullToPrimitive(TypeInfo type) that is called by the AbstractInstanceClassFactory.setValue when the unwrapped value is null and the property info is a primitive.

> Related to JBAS-6188, when a ManagedProperty with a null value that maps to a primitive field in the underlying attachment is saved, an IllegalArgumentException like the following is thrown:
> Caused by: java.lang.IllegalArgumentException: Wrong arguments. setUseTryLock for target org.jboss.resource.metadata.mcf
> .LocalDataSourceDeploymentMetaData at 75687c expected=[long] actual=[null]

> We need to be mapping the null onto the corresponding "0" value for the primitive and writing that.
