Description

Tuscany does not appear to support injecting of CallableReferences with the @Callback annotation.

According to page 11 (lines 682 and 683) of the SCA Java Common Annotations and APIs version 1.0, I should be able to do the following:

@Callback
protected CallableReference<MyCallback> callback;

I downloaded the SCA 0.90 release and updated the simple-callback sample and added the following code to MyServiceImpl:

@Callback
protected CallableReference<MyServiceCallback> m_CallbackReference;

When the code is run, I get the following exception:

It appears that it does not understand using CallableReference and @Callback
