Dunno, this is EJB question not MC. ;-)
Either ask on their forum or check Weld-int 
where, afair, something similar had to be implemented.

This way you get the deployment unit owning the classloader/module,
but to actually get the right deployment unit you would need to check the whole hierarchy of this unit.
e.g.
get class's source location, and check it against unit's and sub-units classpath roots.
