A few more comments on this:
- Guava is so conflict heavy that should avoid using it in the framework
wherever possible. Adding a multiple MBs dependency to write
`Lists.newArrayList` rather than `new ArrayList<>()` also seems a bit much. The
use of the `Joiner` can also be replaced with a `StringBuilder`.
- You can drop the `logback-test.xml` - I think this is an uneeded
artifact that some other modules still have for historic reasons.
- Would be good to also make sure this is put into the `opt` folder in
the build target, so it can be easily dropped into the `lib` folder.
