chore: several files added with CRLF file endings

[tanj]

I noticed when hacking on something that a file I was interested in was committed as CRLF line endings.

This pull request is the result of running find ./ -name '*.java' -exec dos2unix '{}' \; in the repo root.

I totally understand that the diff for these changes are hard to review, so feel free to reject the pull request.
