There is a slight behavioural change in boot 3.2.1 which I had to mitigate in spring-shell and there's a bit more info in https://github.com/spring-projects/spring-shell/issues/961.
In a nutshell some errors are not wrapped in IllegalStateException anymore and spring-shell relied on that. I do like this new behaviour better than the old one but wanted to create this issue as it was an unexpected change.
Also I think existing throw for IllegalStateException is a dead code as exception is always rethrown in handleRunFailure:

The move to using ThrowingConsumer.throwing means that only checked exceptions are wrapped in an IllegalStateException. Any unchecked exception is now rethrown as-is without the wrapping.

We discussed this today and we'd like to leave the new behavior as it is so that we're not wrapping exceptions that don't need to be. We'll open a new issue for the dead code enhancement.
