Ok, update. I can confirm that Bazel does not build with Guava v19. [1] It
looks like `com.google.common.graph.GraphBuilder` is missing, along with
other classes.

Ugh, that *does* sound like quite the pain. I can definitely understand
your preference to stick with something that you know works.

That said, I've uploaded the version 23.6.1 to experimental, and the

Great, thanks! I'll try those! Are you planning to migrate either to
unstable in the near future?

Also, is it possible to concurrently install multiple versions of guava
like we do with some C++ libraries? Sorry if that's a naive question but
I'm not exactly an expert with Java and how we package it in Debian. I know
I've had similar issues in the past with C++ libraries and solved them by
packaging both versions so that I was breaking neither old nor new packages
that depended on them. Then again, I'm not sure if it's practical to do
that with Java.

Please let me know if there's anything else that I can do to help with this!
