Invalid refactor to assertThatThrownBy when returning exception

[fawind]

What happened?

assertj-automation would try to convert org.junit.jupiter.api.Assertions.assertThrows to an assertThatThrownBy assertion when the return value of assertThrows is used:

MyException e = assertThatThrownBy(() -> throwingMethod()).isInstanceOf(MyException.class);

However assertThatThrownBy does not return the exception.

What did you want to happen?

Maybe use catchThrowableOfType instead when the returned exception is used in follow-up code. Arguably, it could also be a hint to refactor the test code to do follow up assertions on the exception with chained methods on the assertThatThrownBy clause.
