Issue #16 Fix space in path issue when invoking xjc

This is the quick fix for the path issue reported in #16 

I can perfectly understand that more than just the change is required, but I admit having no idea where to start with tests for example.

I also included a version change, to replace 1.3.4 with 1.3.5-SNAPSHOT, let me know if this should be removed from the pull request.
