Local callback interface produces incorrect warning message
-----------------------------------------------------------

                 Key: TUSCANY-3251
                 URL: https://issues.apache.org/jira/browse/TUSCANY-3251
             Project: Tuscany
          Issue Type: Bug
          Components: Java SCA Core Runtime
    Affects Versions: Java-SCA-1.5.1
            Reporter: Simon Nash
            Assignee: Simon Nash
             Fix For: Java-SCA-1.5.1


When using a local callback interface together with reference or service 
promotion, the Tuscany runtime produces warning messages for interface 
incompatibility even though the interfaces are compatible.

The following output from samples/implementation-composite demonstrates the 
problem:
