(InMemoryConnector) Sink does not receive message as per Kafka docs

See original GitHub issue

Describe the bug

I’m testing reactive messaging using a Kafka connector.

I want to test with the InMemoryConnector as provided by SmallRye, here and outlined in the related guide on the Testing without a broker section.

FYI @el10686

Expected behavior

The message should be received by the InMemorySink.

Actual behavior

The message is not received at all.

Running the test with ./mvnw clean test -Dtest=InMemoryConnectorTest and awaitility condition check times out with

[ERROR] org.acme.InMemoryConnectorTest.test  Time elapsed: 10.696 s  <<< ERROR!
org.awaitility.core.ConditionTimeoutException: Lambda expression in org.acme.InMemoryConnectorTest that uses io.smallrye.reactive.messaging.connectors.InMemorySink: expected the predicate to return <true> but it returned <false> for input of <[]> within 10 seconds.
	at org.acme.InMemoryConnectorTest.test(InMemoryConnectorTest.java:36)

How to Reproduce?

Here’s a link to a reproducer:
https://github.com/chris-asl/quarkus-reactive-messaging-inmemory

I’ve included two tests:

InMemoryConnectorTest follows the Kafka documentation code but fails, run with ./mvnw clean test -Dtest=InMemoryConnectorTest
InMemoryProducerConsumerTest uses the in memory connector (and passes) but decouples testing of the two components (Consumer, Producer), run with ./mvnw clean test -Dtest=InMemoryProducerConsumerTest
