MultipleContextTest fails on CI

[DavideD]

This test checks that we throw the right exception when session run in the wrong VertxContext.

I cannot figure out why it doesn't fail on CI.

This is the test: MultipleContextTest#persistWithStage

We also need to add tests for the Stateless session (kinda related to #1023)

FWIW

When I run locally with standard out all 4 tests (Stage & Mutiny) log:

STANDARD_ERROR
    [2021-06-03 15:36:17] WARNING io.vertx.core.impl.VertxImpl 
                               You're already on a Vert.x context, are you sure you want to create a new Vertx instance?

Which I assume would be expected

Interesting. We need to figure out why.

Which I assume would be expected

Yes, that's exactly what the test is supposed to do.

[DavideD]

I suppose we should also check the stateless session, though

[DavideD]

Our assertions don't actually check the contexts but the threads. On CI the test run in the same thread and so the exception is not thrown as expected even if the context associated with the session is different than the execution context.

I think we can close this issue, the problem has been solved.
