Sergey Beryozkin commented on CXF-6376:
---------------------------------------

It is a 2.7.x specific regression introduced after I added a support for mapping the exceptions thrown from non JAX-RS (pure CXF) interceptors...

> 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, but no mention about the exception which occured inside the ResponseHandler 
> 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}
