Nix package updates:

- The bisq2 JDK was updated from 23 to 25, and from openjdk to Zulu JDK; Because there seems to be an issue with openjdk 25 and JFX 25.

- The sparrow JDK was updated from 23 to 24. sparrow is currently not compatible with JDK 25.

The problem here is that within a couple of months JDK 22-24 will be dropped from Nixpkgs, which leaves sparrow without a compatible JDK. Yeah, this is all happening again.

I already tested sparrow with the bundled JDK (created with jpackage), which is Temurin JDK 22, and it works. So there's that option.

There's nothing quite like a good game of whack-a-mole.
