Had to update JDK from 11 to 17 to make it build. Should be updated in installation/requirements section of the new flipper, because RN installation guide asks to install 11.

However, now release builds fail.

This is coming from an Android Gradle Plugin constraint. You cannot build against the newer target versions without bumping your JDK. So this is less of a Flipper constraint as it is an Android development one.
