Switching to multi-release JAR broke my assembly build at runtime on Java 17 because it couldn't find LazyCleanerImpl until I added `<Multi-Release>true</Multi-Release>` to the assembled JAR manifest. Might be worth flagging up a bit more in the release notes (wasn't expecting a breaking change in a bugfix release).

```
