Andreas,
Yes my RPC return types are concrete.
please see my project setup below
Proj-gwt (no dependencies)
Src
Com
Acme
AcmeModel.xml (gwt file saying to only use com/acme/client
as source for gwt, no entry point)
Client
AbstractFoo.java
FooImpl1.java
Proj-Other1 (depends on proj-gwt)
Src
Com
Acme
Client
FooImpl2.java (non gwt compliant class, not meant to be
sent across RPC)
Proj-Other2 (depends on proj-gwt and proj-other1)
Src
Com
Acme
AcmeServer.xml (gwt.xml file saying to use com/acme/server
as source for gwt + proj-gwt as a module, contains entry point)
Server
MyService.java (non gwt compliant class, not meant to be
sent across RPC)
Right now when I compile Proj-Other2, of course proj-gwt is also
rolled in, but the compiler tries to get FooImpl2 as well which just
an implementation of AbstractFoo. I never asked it to look for
anything in Proj-Other2.
