Re: [weld-dev] CDI TCK: InvocationContextTest:testGetTarget

The rules on what business method invocations are and aren't should make it clear that invocations on the instance acquired via getTarget() are intercepted, or, for that matter, decorated. Those are *not* business method invocations (in the same way as calls to 'this' are not business method invocations). That behavior is not defined by any specification, unless you can find the section and cite it.
