Error under load "Detected use of the reactive Session from a different Thread..."
See original GitHub issueDescribe the bug
I’m using the reactive dependencies and I’m running into a use case, where I need to store events asynchronously when my REST endpoint gets hit, without blocking the REST call and delaying the response.
I thought, well, that’s easy. Just use SmallRye Emitter, fire an event and the consumer should handle the storing, while the REST call returns the response. Easier said than done, I’m not getting this simple-sounding example to work without this error when I run a load test with up to 20 req/s (error happens much earlier).

Reactive programming is relatively new to me, so it just could be that I’m missing something obvious I have overlooked in the examples.

How to Reproduce?

I’ve created two load-testing scripts that are using k6 in Docker to test both endpoints. Both will fail.
- test-call.sh
- test-invoke.sh
Does not matter which, both lead to the same error.

I’ve described the “workaround” for that issue on it:
I am facing exact same issue when load testing my quarkus application. My application is very similar to this quickstart project - https://github.com/quarkusio/quarkus-quickstarts/tree/main/hibernate-reactive-panache-quickstart. Is there any workaround until https://github.com/quarkusio/quarkus/issues/23300 is fixed?
