Re: [sca-j] [NEW ISSUE] Missing Normative Statements relating to @Callbackannotation used to annotate injection point for callback proxy - [JAVA-159]

[Mike Edwards <mike_edwards@uk.ibm.com>]

Folks,

Good debate.

How about:

  The @Callback annotation MUST NOT appear within
a Java implementation class that has COMPOSITE scope.
  [JCA90052]

Even simpler, but correct and precise.

Dave,
Sorry for not understanding the reason for your concern at the
original wording.

How about the following?

  The @Callback annotation MUST NOT appear on a setter method or
  a field of a Java implementation class that has COMPOSITE scope.
  [JCA90052]

This makes the target of the sentence the class, not the developer.

I didn't agree with your wording change because this doesn't say
explicitly that a class with a @Callback annotation on a setter
method or field of a composite-scoped implementation would not
be a valid SCA Java class as defined in section 12.2.
