Test Binder does not work with Spring Boot 3.3.2 any more #2988

Closed kschlesselmann closed 3 months ago

kschlesselmann commented 3 months ago

After upgrading to Spring Boot 3.3.2 it seems that the OutputDestination does not yield any messages but null any more. If I go back to SB 3.3.1 everything is fine again.

Version of the framework

Additional context I found this question on SO which seems to address the same issue.

Can you please provide a small sample? We have tests that are currently running so I am a bit surprised

@olegz Of course: https://github.com/kschlesselmann/spring-cloud-stream-2988

Just change the SB version to 3.3.1 to make the test pass.

Wondering if it is Kotlin specific. Just tried it with Java and all is good

Ok, figured it out. there was a change in SI to address flux subscriptions - https://github.com/spring-cloud/spring-cloud-stream/commit/3b5bb2e0d9a89c3b9ae9152c99268460ca7ed442 . But it was pushed after the release, so you need to upgrade s-cloud to 2023.0.4-SNAPSHOT or manually upgrade s-c-stream to a 4.1.4-SNAPSHOT
