------------------------------
> NPE when interface extension used with Element API
> --------------------------------------------------

> Key: WODEN-189
> URL: https://issues.apache.org/jira/browse/WODEN-189
> Project: Woden
> Issue Type: Bug

> Attachments: woden189_DescriptionImpl.patch

>
> A null pointer exception can occur when the Element API is used with WSDL
> that contains interface extension. This is because the Element API
> implementation for handling interface extension reuses some of the code
> written to support the Component API, but that code requires that the
> Component model is properly initialized. Specifically, it requires that all
> Interfaces have a reference to their containing Description. The
> initialization of this reference occurs during correct use of the Component
> API. However, if the Element API is used prior to the Component API this
> reference is uninitialized and a NPE will occur.
> This problem was discovered running the Storage-4G testcase from the W3C WSDL
> 2.0 test suite standalone in a Woden test client. The document validator
> attempts to resolve the InterfaceFaultElement for an
> InterfaceFaultReferenceElement and in doing so the Woden implementation uses
> the above mentioned interface extension code. The component model has not
> been initialized at this time (this happens next when the component validator
> is invoked), so the NPE is thrown in
> InterfaceImpl.getExtendedInterface(QName) because the Description reference
> is null.
> A solution is to ensure the component model is initialized as early as
> possible.
