And F-Droid can't install it: https://packages.debian.org/search?suite=all&arch=amd64&searchon=names&keywords=openjdk-19 :(

Is Java 17 not enough anymore?

We really have no intention of reverting back to a older version of java, as we test, develop, and locally build against the latest supported version of java (currently 19 due to kotlin limitations). We cannot guarantee that the code will even work on older versions.

We'd be happy to explore other solutions at the new repo https://github.com/Androidacy/MagiskModuleManager however.
