MarsSeed [1] filed a deletion request for java-16-openjdk [2]: Cleanup of JDK 16 short-term support packages.
JDK 16 is EOL since October 2021; not even security patches get delivered after that date. Users should migrate to a newer JDK/JRE. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/java-16-openjdk/
