I suppose this is to be expected since we are in effect adding several 
annotation-reading methods to the TypeMirror interface that this nominal 
implementation in jaxws doesn't have.

As a stop-gap measure to get the build going, we can make the methods in 
AnnotatedConstruct be default methods, but once we know what API we 
want, we should have the jax-ws team implement those methods in this 
marker object and then revert the default methods to normal one. (As a 
matter of policy, we cannot use default methods in javax.lang.model 
since the API has to be runnable on Java SE 7/JDK 7. [1])

As an aside, should the need arise I'll note that by using annotation 
processors it is possible to generate a compile-time 
JDK-version-specific source for an implementation of an interface.

Cheers,

-Joe
