wsdl2javagenerator and wsdl:import (ebRIM)

This is bug that has been fixed in axis2 as described in this thread

http://www.nabble.com/wsdl-import-failing-with-wsdl2java-axis2-1.3-tf4565180.html#a13030624

and I believe is related to wsdl:import and with wsdl2javagenerator I just get a null pointer
since packageRegistry.values().isEmpty() is empty when tested in
XSD2JavaGenerator

to recreate the problem download the schema and services folder from http://www.oasis-open.org/committees/regrep/documents/3.0/ to create

schema
cms.xsd
lcm.xsd
query.xsd
rim.xsd
rs.xsd
wsdl
ebXMLRegistryBindings.wsdl
ebXMLRegistryInterfaces.wsdl
ebXMLRegistryServices.wsdl

In ebXMLRegistryBindings.wsdl I fixed a typo changing soap:body part to soap:body parts to validate, but this isn't necessary to recreate this problem.

I created a simple ant file as follows to run the wsdl2java task as follows

<project name="tuscany_rim" default="wsdl2java" basedir=".">

Apache Tuscany ebRIM
