Type.Property (ex A.B) and Type (ex AB) Names Collide in Object Factory (jaxbri Code Generation) -- Two declarations cause a collision in the ObjectFactory class

                 Key: AXIS2-4143
                 URL: https://issues.apache.org/jira/browse/AXIS2-4143
             Project: Axis 2.0 (Axis2)
          Issue Type: Bug
          Components: codegen
    Affects Versions: 1.4.1
         Environment: Windows XP (x86), Apache Axis2 1.4.1, Sun JDK 1.5.0_12
            Reporter: Dave Lindquist
            Priority: Minor


When using JAXBRI bindings and generating from a WSDL via wsdl2java.bat, it is possible for a Type.Property and Type name to collide in ObjectFactory.

For example, if my XSD has:
* A type named "Something"
* A type named "Some" with a property named "thing" (and this property is also an "anonymous" complex type)

I will get an error on code generation that says:

[ERROR] Two declarations cause a collision in the ObjectFactory class.
[ERROR] (Related to above error) This is the other declaration.

The bug here is two-fold:
* First, I get absolutely nothing in terms of information that helps me track down WHAT declarations collided (the second message line looks like it was intending to provide that, but it doesn't).
* Secondly, that it collides at all (this is a perfectly valid case, and should be handled in codegen).

I will attach example WSDLs that create this case when generated.

The command line used is:
wsdl2java.bat -o (output directory) -b jaxbri -uri (wsdl file)
