Dennis Sosnoski resolved JIBX-312.
----------------------------------

         Assignee: Dennis Sosnoski
       Resolution: Fixed
    Fix Version/s: JiBX 1.2.2

The 1.2.1 code had several issues in handling non-namespaced schemas, including 
this NPE. Fixed the code generation for non-namespaced schemas and verified it 
now works with the sample schema.
