Subject: [sca-j] JAVA-17: Proposed resolution

The resolution of JAVA-55 has clarified the rules for which setter
methods are taken into account when introspecting for properties
and references.  The relevant text is as follows:

 The following setter methods and fields are taken into consideration:
  1. Public setter methods that are not part of the implementation of
     an SCA service (either explicitly marked with @Service or implicitly
     defined as described above)
  2. Public or protected fields unless there is a public setter method
     for the same name

Point 1 above makes it clear that the "setX" examples given in the JIRA
are not properties or references.

The JIRA also raises the following question.
 "Another question would be: Is it valid to have a setter method
  denote both a property/reference and business operation?"

For introspected properties and references, the text in point 1 above
rules out this possibility.  However, the possibility does exist for
properties and references specified by explicit annotations, for example:

 public class MyServiceImpl implements MyService {
     public void setX(String x) {

 public interface MyService {
     void setX(String x);

I believe this could be useful in some cases and should not be

I therefore propose that this issue should be closed as having been
resolved by JAVA-55.
