Paper/patches/server/1015-Registry-Modification-API.patch
Bjarne Koll 9c450388e1
Return null in getRegistry(Class) for unknown type (#11422) 
The Bukkit#getRegistry(Class) method contract specifies that it returns
null for unknown registry types. The current implementation however
requires the passed class to be mappable to a known registry key.

For types like Material, which have a SimpleRegistry in bukkit's
Registry interface, no server side registry exists and such the type
cannot be mapped to a registry key.

The commit correctly returns null for types that are not mappable to a
registry key instead of throwing a NullPointerException.
