I was pleasantly surprised about 6 months ago when I went to run a game I wrote in Java when I was at university. Nothing huge, but still about 10k lines of code. I originally wrote it in Java 6, and it compiled and ran with no issues on Java 20. I only used one 3p lib, otherwise just the standard library, which helped, but I was expecting something to be broken given it was over 10 years later.
