SYNOPSIS
--------
ModelerException from wsgen

OPERATING SYSTEMS
-----------------
All

FULL JDK VERSIONS
-----------------
Java 6 and above, including latest JDK 8 build.
Also reproducible with the latest JAX-WS RI.

PROBLEM DESCRIPTION
-------------------
If an implementation class extends a class which has the web method definition declared in the end point interface, wsgen fails with a ModelerException.

The problem does not occur it we implement the web method in the sub class, but, according to the JAX-WS specification, we should not have to implement a web method that is implemented in the super class.

The relevant part of the specification is JSR-181 section 4.1, which says:

        The complete name of the service endpoint interface defining the
        service's abstract Web Service contract. This annotation allows the
        developer to separate the interface contract from the implementation. If
        this annotation is present, the service endpoint interface is used to
        determine the abstract WSDL contract (portType and bindings). The
        service endpoint interface MAY include JSR-181 annotations to customize
        the mapping from Java to WSDL. The service implementation bean MAY
        implement the service endpoint interface, but is not REQUIRED to do so.

REPRODUCTION INSTRUCTIONS
-------------------------
1) unzip wsgen_recreate.zip
2) cd src
3) javac *.java
4) wsgen -keep -d gen -s src -cp .; -wsdl TestSubImpl

wsgen will fail with the following Exception (this specific trace is from 7u9):

TESTCASE
--------
Attached.

WORKAROUND
----------
Override the webmethod again in the sub class, even if it is overridden in the super class.
