Ok I found out the problem. In my previous attempts, I tried with this
signature:
@GET
public GenericEntity<Collection<T>> list() {
return new GenericEntity<Collection<T>>(resources.values()){};
}
I tested with this code yesterday, which is failing.
With the simple signature:
@GET
public Collection<T> list() {
return resources.values();
}
Everything is now working fine.
BR,
Thibaut
