Can you provide an example where Google Guava broken backwards compatibility? I have used it for more than 10 years without any issues during upgrades. To be fair, it is a huge library, and I have probably barely used 20%.

Oh, this is common. Fun when you have two different dependencies which both use Guava, but different versions, and you can't upgrade them to a common shared one. The solution there usually means having to shade Guava for one of them, which sucks, but it at least gets things working.

It's not much of a problem when you use it yourself, but it is when your dependencies do.
