[sca-j] [NEW ISSUE] A hole in the algorithm of introspecting property/referencefrom an unannotated impl class

[Raymond Feng <rfeng@us.ibm.com>]

TARGET:  Java Component Implementation Specification

DESCRIPTION : 

The spec says:

358 1.2.7. Semantics of an Unannotated Implementation
359 The section defines the rules for determining properties
and references for a Java component
360 implementation that does not explicitly declare them
using @Reference or @Property.
361 In the absence of @Property and @Reference annotations,
the properties and references of a class are
362 defined according to the following rules:
363 1. Public setter methods that are not
included in any interface specified by an @Service annotation.
364 2. Protected setter methods
365 3. Public or protected fields unless there is a public
or protected setter method for the same name

To apply the rule to the following case:

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

@Remotable
public interface MyService {
        void setX(String
x);
}

"x" will be taken as a property as it's NOT
in any interface specified by @Service which is not present at all. But
"setX()" is also an operation for the service "MyService
".

It's also tricky for the following case:
public class MyServiceImpl {
        public
void setX(String x) {
         
      ...
        }
}

The service type will be MyServiceImpl.class. Would "x"
be treated as a property or "setX()" as a business operation?

Another question would be:  Is it valid to have a
setter method denote both a property/reference and business operation?

PROPOSAL: 

Change the text to:

363 1. Public setter methods that are not included in
any interfaces from services introspected
from this implementation class

Thanks,
Raymond
