I was trying to generate client classes for https://www.onvif.org/ver10/deviceio.wsdl with wsdl2java and got the following:
Exception in thread "main" java.lang.InternalError: unresolved reference

According to this SO question, it is related to a type reference. This is a large WSDL file with many imports. Could anyone offer a tip about a practical way to
find the culprit?
