So is the minecraft codebase terrible? I would guess it is based on the classes of bizarre bugs that seem to exist. I could almost believe Bethesda had a hand in its development.
I'm guessing Mojang is worth at least a Billion dollars because they make second most popular computer game in history; I'll take that kind of "terrible" any day of the week and consider myself blithely lucky.
There are some very terrible coding decisions made within the minecraft community.
The open source server (which is based I believe on the orginal server) actually doesn't use function names to describe what the function does, but functions are given names like, "a","b","c","d" in alphabetical order.
The upstream minecraft server is a JAR that was run through a Java bytecode obfuscator, which mostly works by renaming all functions and fields with names like that. I'm not aware of any open-source server built with such unreadable naming from the start, but there are definitely _decompiled_ versions floating around. Since the original JAR was obfuscated, these decompiled versions are only partially deobfuscated, if at all, hence the unreadable names.
