Blocked thread if WebApplicationException is reused. #4097

kingsfleet · 2019-04-11T15:24:37Z

I think this exception has been raise a few times; but it never seems to come with a reproducer so the scenario is that after a while there is a number of stuck threads noted in this case by WLS 12.2.1; but I can see that this code would be a problem in the servers:

#3474

None of these appear to have a reproducible test case, so I have raised this bug in case they are separate concerns.

This behaviour is seen in our code when a WebApplicationException is rethrown by a Guava Cache but the Response in this case is no longer valid as it has previously been used or is in use.

        Response r = Response.status(this.getStatus())
                        .type(getMediaType())
                        // Make it more detectable that someone is trying to re-use this response object
                        // by causing an stream closed IO Exception, do not remove please consult
                        // BUFP-29699 as to why this is a good idea
                        .entity(new StringReader(toJSON()))
                        .build();
        throw new WebApplicationException(response);

Note originally the response was a string; but the problem became more reproducible when we use an entity that cannot be re-used; but it isn't required.

Of course Response is an instance of OutboundJaxrsResponse which holds and instance of OutboundMessageContext which in turns holds a CommittingOutputStream which is not re-usable.

Depending on the load you either see two thread using the CommittingOutputStream at once or errors due to closed streams. It most cases the client in unaware of what has gone wrong and that makes it much harder to track down. Not sure how it gets the right response in this case.

So the deadlock happens in this section of code in SeverRuntime.java:

            try {
                response.setStreamProvider(new OutboundMessageContext.StreamProvider() {
                    @Override
                    public OutputStream getOutputStream(final int contentLength) throws IOException {
                        if (!runtime.disableLocationHeaderRelativeUriResolution) {
                            ServerRuntime.ensureAbsolute(response.getLocation(), response.getHeaders(),
                                    response.getRequestContext(), runtime.rfc7231LocationHeaderRelativeUriResolution);
                        }
                        final OutputStream outputStream = writer.writeResponseStatusAndHeaders(contentLength, response);
                        return isHead ? null : outputStream;
                    }
                });

                if ((writer.enableResponseBuffering() || isHead) && !response.isChunked()) {
                    response.enableBuffering(runtime.configuration);
                }

                try {
                    response.setEntityStream(request.getWorkers().writeTo(
                            entity,
                            entity.getClass(),
                            response.getEntityType(),
                            response.getEntityAnnotations(),
                            response.getMediaType(),
                            response.getHeaders(),
                            request.getPropertiesDelegate(),
                            response.getEntityStream(),
                            request.getWriterInterceptors()));
                } catch (final MappableException mpe) {
                    if (mpe.getCause() instanceof IOException) {
                        connectionCallbackRunner.onDisconnect(processingContext.asyncContext());
                    }
                    throw mpe;
                }
                tracingLogger.log(ServerTraceEvent.FINISHED, response.getStatusInfo());

                            // output streams writes out bytes only on close (for example GZipOutputStream).
                            response.close();
                        } catch (final Exception e) {
                            LOGGER.log(Level.SEVERE, LocalizationMessages.ERROR_CLOSING_COMMIT_OUTPUT_STREAM(), e);
                        }
                    }
                }
            }

For example if the code in response.enableBuffering(runtime.configuration); fails because someone has already started to use the buffer you end up in the Throwable block before the code in setStreamProvider is executed. This means that when you get to response.close() it eventually get suck in ResponseWriter.commit but the ResponseContext is never set.

So it would make sense if the .get on the future this ResponseWriter had some kind of timeout; but it would be even better if the code properly recovered from this situation. As I say this is a hard was to track down because if the requirement for concurrency and for re-using the same Response object.

I can demonstrate this working in a running system if it helps with a fix, for the moment we worked around this using a trivial subclass:

  /**
     * Provide access to the internal state of the error without having to re-parse the entity body with
     * the problems this entails.
     */
    public static class DetailWebApplicationException extends WebApplicationException {

        @Getter
        private final ExceptionDetailResourceType type;

        /*package*/ DetailWebApplicationException(ExceptionDetailResourceType type) {
            super(type.toResponse());
            this.type = type;
        }

        @Override
        public Response getResponse() {
            // You cannot reuse a response, and in some cases when the exception is cached we find that
            // the exception was being resent to the user causing a thread leakage due to a design flaw
            // in the Jersey runtime, please consult BUFP-29699 before modifying this code.
            return type.toResponse();
        }
    }

But it might be possible to use an interceptor to clone the Response; but I didn't try it.

The text was updated successfully, but these errors were encountered:

So we ran into the same issue where our threads end up blocked in waiting state and connections in CLOSE_WAIT. This happened with this exception : "An I/O error has occurred while writing a response message entity to the container output stream". For now, we found out the source of these exceptions and fixed it but code should be able to gracefully handle such scenarios and not build up the blocked threads infinitely.

This happens when we see this error:

jbescos · 2020-12-04T09:38:47Z

How is that WebApplicationExceptionre used by guava cache?. It contains a response, so that exception should never be cached/reused.

alishaarora · 2020-12-04T18:00:35Z

@jbescos Agreed that the response shouldn't be reused. Contrary to the original issue by the reporter, we were not using Guava yet at one point we were reusing the response leading to this scenario. Even then, shouldn't jersey gracefully recover from this situation (or throw exception) rather than having threads wait infinitely?

jbescos · 2020-12-07T08:58:32Z

I think we can set a configurable timeout for the CompletableFuture.get in the line:
org.glassfish.jersey.servlet.internal.ResponseWriter.getResponseContext(ResponseWriter.java:275) at

So it will not be hanged forever.

alishaarora · 2020-12-08T04:18:54Z

@jbescos Yes this should prevent the threads from hanging forever. We had tried it in our server and it prevented the increase in waiting threads thereby alleviating the problem. It will be sufficient although it would be better if in case of an exception in setStreamProvider(), it is handled immediately (in addition to adding timeout).

alishaarora · 2021-01-12T16:58:08Z

@jbescos Which version will this change go in?

jbescos · 2021-01-13T08:52:57Z

@alishaarora sorry for not reply for quite some time. I was discussing this with @jansupol and we decided to not do anything yet.

There are two reasons for this:

The base issue is caused by incorrect user code (reusing the response is not correct), then the fix should be done in user code. This makes this is issue with low priority.
We would like to have a reproducer, so we can know in detail the issue and verify possible solutions.

alishaarora · 2021-01-13T09:17:12Z

@jbescos Thanks for the reply.

Yes the correct fix should be done in user code but can we atleast add a timeout at org.glassfish.jersey.servlet.internal.ResponseWriter.getResponseContext(ResponseWriter.java:275) like you suggested earlier so it prevents the threads from hanging forever? None of the timeouts are honored here and trying to get response context when it can never come back seems odd.
The issue is easily reproducible by reusing the response (there might be other ways to reproduce where output stream is already closed)

jansupol · 2021-01-13T11:30:11Z

The issue is easily reproducible by reusing the response (there might be other ways to reproduce where output stream is already closed

I really wished it would be that simple. If you have that simple reproducer, please add it here. We already spent some time on the reproducer without a success.

migedt · 2022-04-09T16:33:58Z

I created a simple reproducer here: https://github.com/migedt/jersey-issue-4097-reproducer

jbescos · 2022-04-11T06:47:13Z

I get the thread blocked in your example, but I don't get it blocked when I execute the next test:

public class Issue4097Test extends JerseyTest {

    @Override
    protected Application configure() {
        return new ResourceConfig(Issue4097Resource.class);
    }

    @Override
    protected TestContainerFactory getTestContainerFactory() throws TestContainerException {
        return new JettyTestContainerFactory();
    }

    @Test
    public void reuseResponse() throws InterruptedException {
        WebTarget webTarget = target("/issue4097/reuseResponse");
        assertEquals(410, webTarget.request().get().getStatus());
        System.out.println("Received 2nd response (200): " + webTarget.request().get().toString());
        System.out.println("Received 3rd response (hangs): " + webTarget.request().get().toString());
    }

    @Path("/issue4097")
    public static class Issue4097Resource {

        private static final Response RESPONSE =
            Response.status(410).entity("test").build();

        @GET
        @Path("/reuseResponse")
        public Response reuseResponse() {
            // returning the same response is obviously wrong
            return RESPONSE;
        }
    }

}

Anyway, I will review this. Ideally in the second request it should throw one exception.

I am attaching both relevant threads in your example:
