Don't support phased schema generation

JiBX use in the project has identified a problem, described as follows:
Pre-conditions:
1, Project A use projecta.xsd and commons.xsd, Project B use projectb.xsd and commons.xsd.
2, The commons.xsd in project A and Project B is the same schema.
3, projecta.xsd and commons.xsd with JiBX generated by the use of Java type and packaging, and work normal (pa.jar)
4, projectb.xsd and commons.xsd with JiBX generated by the use of Java type and packaging, work normal too (pb.jar)

Question:
I put the pa.jar and pb.jar in the same jvm ,then report error.
Cause pa.jar and pb.jar all have the classes generated from commons.xsd ,and they don't have the same byte-code.
