Some of these were wrong (scoreboard manager), others are counter to
everything everyone expects (Locations world being null, which wasnt ever safe EVER)
others are just too noisy.
Replace some with Contract to get rid of the nullability constraint and go back to
the old days of IDE not considering it strictly one way or the other.
Also, stop requiring annotations on package-private.
Introduces the next Developer Perk for Paper-API: Your plugin isn't yellow anymore.
Also fixed random dupe code in ensureServerConversions that got mistakenly set in the update.
Upstream has released updates that appears to apply and compile correctly.
This update has not been tested by PaperMC and as with ANY update, please do your own testing
Please note that this build includes changes to meet upstreams
requirements for nullability annotations. While we aim for a level of
accuracy, these might not be 100% correct, if there are any issues,
please speak to us on discord, or open an issue on the tracker to
discuss.

This was a useless exception wrapper that ends up making
stack traces harder to read as well as the JVM cutting off
the important parts
Nothing catches this exception, so its safe to just get rid
of it and let the REAL exception bubble down
