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

Such error can silently break the application:

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();
	}

}
