Re: [sca-j] JAVA-153: Proposed resolution rev3
Ok, I hadn't realized that callback had already set a precedent.  I still stand by my assertion that the componentType should be a reflection of the implementation artifacts, but I don't want to argue against an existing precedent at this point in the spec lifecycle.

BTW, I don't see this as redundant info, I see it as the means for tooling to ensure the component shape contract without having to look at the implementation artifacts.

Re: [sca-j] JAVA-153: Proposed resolution rev3

Folks, 

My view is that IF the interface class is annotated @Remotable then it is *NOT* necessary 

to introspect the component type of a service or reference which uses that interface class 

such that the <interface.java/> element contains the @remotable attribute set to true. 

I think this is consistent with other places where the interface class contains other forms of 

annotation.  @Callback is the best example in my opinion - here the interface class can 

contain @Callback and reference a callback interface, but the introspected componentType 

simply has a <interface.java/> element which references the interface and it does not 

require the callback interface to be referenced as well and yet the interface is still treated as 

a callback interface. 

I agree with Simon's view that redundant information is undesirable. 

Yours,  Mike.
