I did not run ubi, because the build tools 33 use d8 instead of dx now but ubi itself seems to have dx hardcoded in some places.

Seems like the build failed because the KSPASS variable was missing in the CI pipeline. Not really sure why though.

I'd like to delay merging this until we have rebased to a more recent version, as these changes might cause tricky to debug issues, for which one reason may be an outdated base.

dirty workspace?

TokenizerTest still uses these functions

bttv/mod/app/src/test/java/bttv/mod/TokenizerTest.java

Line 176 in b72a813

System.out.println("name: " + ((MessageToken.EmoticonToken) token).component1());

Although in hindsight adjusting the test would probably be the better way forward.

Sounds good to me, as it mostly touches files that aren't usually changed in rebases it shouldn't be a problem to do this later.
