I'm using 2.1-RC1
I have a resource interface with a get method which returns an enum: DrState.
I have included a callback signature in the interface:
@Get("json")
DrState getDrState();
@Get("json")
void getDrState( Result<DrState> callback );
When I use the synchronous version, everything works. If I use the callback
version, I see an exception logged and onSuccess() is called with null.
Running in the debugger and looking at the code, I see in
org.restlet.engine.resource.ClientInvocationHandler<T>:
result = getClientResource().toObject(
response.getEntity(),
actualType.getClass());
At this point, actualType is correctly the class of my enum. However,
actualType.getClass() is Class.class.
Based on my (limited) reading of the code, I think this should be passing
actualType instead of actualType.getClass().
The logged stack trace:
Unable to parse the object with Jackson.
