Vojtěch Krása updated CXF-6376:
-------------------------------
    Description: 
quickstart: https://github.com/krasa/cxf-bug
mvn jetty:run
GET http://localhost:8080/cxf/rest/foo
-> 200 is returned, while the log prints javax.ws.rs.NotFoundException


Such error can silently break the application:
{code}
import javax.ws.rs.core.Response;

import org.apache.cxf.jaxrs.ext.ResponseHandler;
import org.apache.cxf.jaxrs.model.OperationResourceInfo;
import org.apache.cxf.message.Message;

public class ErrorResponseHandler implements ResponseHandler {

        @Override
        public Response handleResponse(Message m, OperationResourceInfo ori, 
Response response) {
                System.out.println("throwing NPE");
                throw new NullPointerException();
        }

}
{code}
