Incorrect return type of Kotlin suspending functions [SPR-16515]

[spring-projects-issues]

Konrad Kamiński opened SPR-16515 and commented

The return type of Kotlin suspending functions (as returned via getParameterType() and getGenericParameterType() methods of MethodParameter) is incorrect. The true return type is actually a generic type of the last parameter of the method.

This issue affects spring-kotlin-coroutine library, specifically issues #10 and #14.

This issue is related to #19975.

Since we have not been able to progress on the question raised on the PR, and given the fact I would like to propose supporting Coroutines for 5.2, I think it is better to target 5.2 as well for that one.
