Java 21 on flatpak

[Munteanujasmin09]

How i can install java 21 on flatpak version of pollymc?

Go to this site https://jdk.java.net/archive/ and grab the 21.0.2 version, extract it in the data folder of the flatpak folder (something like $HOME/.var/app/org.fn2006.PollyMC/data), in the Java settings select the folder you extracted, go to bin and select java, it should work now
