MarsSeed [1] filed a deletion request for jdk10-openj9-bin [2]: Cleanup of deprecated JDK 10 short-term support packages.
JDK 10 and its Eclipse OpenJ9 (formerly IBM Semeru) builds are EOL since October 2018. No support or updates / security fixes available. Users should migrate to a newer JDK/JRE. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/jdk10-openj9-bin/
