JZlib not in the classpath

Open hantsy opened this issue 8 months ago • 12 comments

I tried to clean up my Vertx example project to Vertx 5.0.0, when cleaning the Rxjava3 examples, encountered an issue.

The codes used to start a HTTP server is like this:

  return vertx.createHttpServer()
      .requestHandler(router)
      .rxListen(8888)
      .doOnSuccess(server -> {
          log.info("HTTP server started on port " + server.actualPort());
      })
      .doOnError(throwable -> {
          log.error("Failed to start HTTP server:" + throwable.getMessage());
      })
      .ignoreElement();

And I defined a simple /hello endpont in the router.

router.get("/hello").handler(rc -> rc.response().rxEnd("Hello from my route"));

Version

Windows 10 Pro vertx 5.0.0 Java 21

Context

I encountered an exception which looks suspicious while hiting the hello endpoint

Do you have a reproducer?

  • https://github.com/hantsy/vertx-sandbox

Steps to reproduce

  1. git clone https://github.com/hantsy/vertx-sandbox
  2. cd vertx-sandbox
  3. docker compose docker-compose.yml
  4. cd rxjava3
  5. mvn clean package exec:java -DskipTests
  6. Or java -jar ...-fat.jar after build

can you provide a reproducer that does not use docker compose ?

vietj avatar May 16 '25 06:05 vietj

@vietj Create a new project from scratch, see this attchment.

rxjava3-issue.zip

hantsy avatar May 16 '25 07:05 hantsy

how does that work ? I ran mvn test and everything worked

vietj avatar May 17 '25 08:05 vietj

What OS you are using?

I was using Windows 10.

Let's wait for others to confirm this.

hantsy avatar May 17 '25 09:05 hantsy

@vietj The test is empty.

Run the project via mvn clean package exec:java

Or run in another terminal java -jar xxx-fat.jar after build.

Then hit the /hello endpoint via curl http://localhost:8888/hello

This does not seem to be an exception to me, it is just a log line that explain that JZlib is not available and is not an error

vietj avatar May 17 '25 11:05 vietj

Yes, but the endpoint is blocked, no returned result.

hantsy avatar May 17 '25 12:05 hantsy

When searching JZlib in rxjava3 github sources, can not find such a dependency.

hantsy avatar May 17 '25 13:05 hantsy

ah it works for me on OSX

I don't have windows, can you can you try debug it ?

vietj avatar May 17 '25 15:05 vietj

Step into the calling stack, got the exception in the console.

is that reproducible on non windows ?

vietj avatar May 22 '25 12:05 vietj

@vietj Also tried to use curl on Github actions workflow for the original project which runs on an Ubuntu.

- name: Test with CURL
  run: |
      mvn clean package exec:java -DskipTests --file rxjava3/pom.xml & 
      sleep 10
      echo ">>> print cURL result <<<"
      curl http://localhost:8888/hello &

And got the following logging. It seems to be blocked.

>>> print cURL result <<<

Hi @hantsy

It seems the issue is with the route definition.

If you change:

router.get("/hello").handler(rc -> rc.response().rxEnd("Hello from my route"));

To:

 // Must subscribe because computations are lazy with `rxEnd`
router.get("/hello").handler(rc -> rc.response().rxEnd("Hello from my route").subscribe());

Then the problem goes away.

I'm not sure how this is specific to 5.0, because the same behavior applies to 4.5.

Anyway, I'll close the issue but feel free to send more comments/questions

tsegismont avatar Dec 19 '25 15:12 tsegismont

I will verify it, thanks for debugging it.

Ideally, for reactive case, it should not call the subcribe explicitly.

When an Http Client connects to this endpoint, it will trigger a subcribe method implicitly.

hantsy avatar Dec 20 '25 02:12 hantsy

You can't have automatic subscription with the Route.handler method, but it should work with Route.respond

See https://vertx.io/docs/apidocs/io/vertx/reactivex/ext/web/Route.html#respond(io.reactivex.functions.Function)

tsegismont avatar Dec 20 '25 08:12 tsegismont

I am not sure how Vertx handle the http client connection. In Spring reactive stack, we can always return a Mono/Flux type directly, when a client connects to the endpoint, Spring framework will let the client subscribe to the server reactive data stream.

hantsy avatar Dec 22 '25 02:12 hantsy

// Must subscribe because computations are lazy with rxEnd router.get("/hello").handler(rc -> rc.response().rxEnd("Hello from my route").subscribe());

BTW, thank you for the solution.
