Bug description

The library com.annimon.stream ( https://github.com/aNNiMON/Lightweight-Stream-API ) is used as a polyfill for the Java 8 steams API -- but the streams API is also used. We don't need to have both.

I'm glad to work on a PR for this (it's pretty mechanical), but in case it's something the team wants to do themselves, I'm opening an issue first.

Hi! I'm happy for you to work on this but given the sheer number of files this would touch ask that you do it piecemeal. Otherwise it makes it hard on us to have high confidence in the changes.
