Im guessing this is due to Minecraft updating the java requirements. I assume this is to allow older builds to be able to run on the same servers as newer builds?

Yes, this is to allow older builds or other Java dependent applications to be able to run on the same server. Because Minecraft is expecting the newest Java JDK 16, many servers I manage or know of will have dependency issues.

Yes. The JDK 16 update has proven to cause trouble when using e.g. crontab to schedule mcserver monitor commands, etc.
