Cannot invoke method on Service that implements multiple @Remotable interfaces 
with methods of the same name
------------------------------------------------------------------------------------------------------------

                 Key: TUSCANY-2180
                 URL: https://issues.apache.org/jira/browse/TUSCANY-2180
             Project: Tuscany
          Issue Type: Bug
          Components: Java SCA Core Runtime
    Affects Versions: Java-SCA-1.1
         Environment: SVN Revision 643322
Linux
            Reporter: Mark Combellack
            Assignee: Mark Combellack
             Fix For: Java-SCA-Next


When a Component implementation class implements multiple @Remotable interfaces 
which have methods with the same name, it is not possible to invoke the 
duplicate method name on the second Remotable interrface.

Consider the following example:

I have two @Remotable services as defined by the following Java interfaces:

@Remotable
public interface LocalTimeService {
    Date getCurrentTime();
}

@Remotable
public interface WorldTimeService {
    Date getCurrentTime(String timeZone);
}


I have a single Java Component that implements both of these @Remotable 
Interfaces:

@Service(interfaces = {LocalTimeService.class, WorldTimeService.class})
public void class TimeServiceImpl implements LocalTimeService, WorldTimeService 
{
    public Date getCurrentTime() {
        // Code not shown
    }

    public Date getCurrentTime(String timeZone) {
        // Code not shown
    }
}


If I invoke getCurrentTime(), the code will work

If I invoke getCurrentTime("GMT"), the code will fail. The stack trace is:
