- Unfortunately, during the development of https://github.com/termux/termux-packages/pull/25127, `libcommons-lang3-java` was auto-updated to the same version as in my branch, and when I rebased and merged my branch, the automerge automerged the two bumps into the same version, but this has unfortunately prevented the change of dependency of `libcommons-lang3-java` from `openjdk-17` to `openjdk-21` from deploying into the mirror.
- Fixes https://github.com/termux/termux-packages/issues/25027
- JDK 21 has been released for a year, so theoretically, all packages should be ready now, but it will be necessary to test each package's basic functionality with `openjdk-21` installed, to make sure that they are compatible.
- Now that https://github.com/termux/termux-packages/pull/25214 has been merged, it should be easier for termux-apt users whose `java` command is set to `openjdk-17`, to get it automatically updated to `openjdk-21` without necessarily having to uninstall `openjdk-17`.
