@mstepan Thanks for posting.

There seems to be some version conflict happening. Can you post your Gradle or POM file?

First guess: jqwik 1.9.0 is made with JUnit platform 1.10.x (so it pairs with Jupiter 5.10.x). I don't do backwards compatibility testing below JUnit's minor version (5.10.0).

On further research: Starting with jqwik 1.8.0 (released in September 2023), JUnit 1.10 is the minimum required platform version.

It might work with JUnit 1.6.x, but that's just guessing.

I can confirm that with junit 5.10.x it's working.
