Re: [jersey-dev] [External] : Jersey 2.40 - compatibility with IBM WebSphere Liberty Profile
Hi Jan,

thanks for the quick response, in our application we're actually not actively utilizing jerseys ContainerResponseFiltering or ContainerRequestFiltering. I also already stumbled upon the enableBuffering and commitStream parameters of the ContainerResponse class during research, but up until now, we didn't experience such a problem (before we switched to Websphere Liberty Profile).

Also, the problem seems to be related to identical requests sent within a few milliseconds. Could this be some sort of timing or caching problem in jersey?

Due to an error in our mobile app, we receive 2 same requests on one of our endpoints at one such occasions were a thread afterwards stays waiting as can be seen here:
16211829 04-03-2024 21:16:57.313 [Default Executor-thread-94] [C:] INFO  <stripped information> "restPath":"/anonEndPoint"
16211831 04-03-2024 21:16:57.315 [Default Executor-thread-94] [C:] INFO  <stripped information> "restPath":"/anonEndPoint"

And next we see this in the messages.log of WLP:
16211840 2024-03-04 21:16:57,324 [Default Executor-thread-94] ERROR o.g.j.s.ServerRuntime$Responder - An I/O error has occurred while writing a response message entity to the container output stream.

We already removed the erroneous code that caused those multiple requests and are currently waiting for it to become available to our users, hoping it will mitigate the "waiting thread"-problem, but as we were not able to reproduce the behavior on our side we can't be sure, that this really fixes it.

Hi, 
Yes the "java.lang.IllegalStateException: Cannot setup buffering as bytes have already been written to the output stream. The entity buffering can be initialized only before first bytes are written to the entity output stream" is the source of the thread being stucked.

But from the stacktrace, it is hard to see what's the reason of this. There could be two similar reasons I can see. The Jersey ContainerResponse has invoked either:
  1. enableBuffering
  2. commitStream
during ContainerResponseFiltering stage. (Or there is some other reason I cannot see right now). Is it possible that either of your ContainerResponseFilter casts ContainerResponseContext to ContainerResponse and utilize any of the two methods?

Subject: [External] : [jersey-dev] Jersey 2.40 - compatibility with IBM WebSphere Liberty Profile
 
Hello,

For our latest release we migrated our software from Java 8 and WebSphere Traditional to OpenJDK 11. During this migration we upgraded some of our used libraries and Jersey was one of it - we migrated from 1.19.4 to 2.40 with the following components:

<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-common</artifactId>
    <version>2.40</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.40</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-server</artifactId>

</dependency>
<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-jaxb</artifactId>
    <version>2.40</version>
</dependency>

The used version of WebSphere Liberty Profile at the time of writing this is: WebSphere Liberty Profile 23.0.0.7 (JEE8)

During internal testing no obvious problems happened with Jersey on our internal systems, but on the productive environment things started going bad. 

Over some hours we experience a rising amount of threads switching to a waiting status and never recovering. The stacks of the threads vary only in 2 lines and are otherwise the same - see below:

So it seems that the threads are all waiting on a CompleteableFuture, but in our implementation of the endpoints, we don't use it, so it seems to be happening internally inside the Jersey library.

Another log-excerpt I found, which is probably related to the mentioned threads which are in this waiting status is the following:

53115079 2024-02-19 20:33:28,012 [Default Executor-thread-65753] ERROR o.g.j.s.ServerRuntime$Responder - An I/O error has occurred while writing a response message entity to the container output stream.

I searched a bit, but didn't find any direct relation to problems with WebSphere Liberty Profile and compatibility of jersey 2. Does anyone exprerience something similar or does have a clue on how to prevent it from happening?

Thanks in advance for your input.

best regards,
Manuel
