---------------------------------

             Summary: Annotation inheritance does not work if a non JAX-RS annotation is present on an implementation method
                 Key: CXF-5066
                 URL: https://issues.apache.org/jira/browse/CXF-5066
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 2.7.5
            Reporter: Simon Gerber
            Priority: Minor


Consider an annotated interface and implementation as follows

{noformat}
@Path("example")
public interface Example {
     
    @GET
    ExampleResponse get();
}

public class ExampleImpl {

    @Override
    public ExampleResponse get() { // ... }
}
{noformat}

In the above example CXF will reject this resource ResourceUtils.createClassResourceInfo() fails to find any dispatcher methods. 

The reason for this is that AnnotationUtils.doGetAnnotatedMethod() returns the concrete class method because it has an Override annotation on it. Therefore it does not find the method annotation.

The workaround is to remove the Override annotation - however since many IDEs (such as Eclipse) are configured to add this by default it could be considered a case where user expectations will not be met. This caveat was not documented anywhere and it required debugging into the CXF source code to isolate the issue.
