Karl M. Davis commented on CXF-5980:
------------------------------------
My code above had a very simple mistake that was preventing it from working.
Thanks *very* much for your testcase, which helped me figure that out-- never
would have caught it, otherwise.
The problem is the parameter that I was passing in to the {{GenericType}}
constructor. Just removing that constructor argument fixed things.
This was broken:
{code}
List<GameSession> games = response.readEntity(
new GenericType<List<GameSession>>(GameSession.class)
{});
{code}
And this works:
{code}
List<GameSession> games = response.readEntity(
new GenericType<List<GameSession>>() {});
{code}
(My apologies for the long delay in my response-- I only made it back to the
TODO in my code that I'd left for this last night.)

> The following code fails:

> {code}
> With the following root exception (I'll attach the full log out/stack tracce

> {code}
> javax.xml.bind.UnmarshalException: unexpected element
> (uri:"http://justdavis.com/karl/rpstourney/api/schema/v1";,

> <{http://justdavis.com/karl/rpstourney/api/schema/v1}account>,<{http://justdavis.com/karl/rpstourney/api/schema/v1}gameRound>,<{http://justdavis.com/karl/rpstourney/api/schema/v1}gameSession>,<{http://justdavis.com/karl/rpstourney/api/schema/v1}player>
> ... 93 common frames omitted
> {code}
> This is the first time I've tried to pull a generic/collection object out of
> a Response using CXF's JAX-RS 2.0 client, so my guess is that this is just an
> unsupported edge case? For what it's worth, the server-side of the web
> service being queried is hosted by the same version of CSF and handles this
> just fine-- only the client seems to have issues.
