Re: [sca-j] [ISSUE 157] Section 10.13 on @OneWay requires a normativestatement - Updated Proposal

[Simon Nash <oasis@cjnash.com>]

Mike,
I agree with making this change.  I believe some additional spec
changes are also needed.

To remove the capability for Java classes to specify @OneWay, we
need the following additional spec changes:

1. In Java CI, change the first sentence of section 2.4 to:
     Service operations defined by a Java interface can use the
     @OneWay annotation ....

2. In the second paragraph of section 7.3 of Java CAA, change
    "Any method with a void return type ...." to "A method with a
    void return type ...."

To clarify that @OneWay is needed on both the service interface
and the reference interface, we need to say something like the
following somewhere in the Java CAA spec:

  x.x Compatibility of Java Interfaces

  The SCA Assembly Model specification [ASSEMBLY] defines a number
  of criteria that need to be satisfied in order for two interfaces
  to be compatible or have a compatible superset or subset relationship.
  If these interfaces are both Java interfaces, compatibility also
  requires every method that is present in both interfaces to be defined
  consistently in both interfaces with respect to the @OneWay annotation,
  that is, the annotation is either present in both interfaces or
  absent in both interfaces.
