The CraftBlockStateMeta constructor CraftBlockStateMeta(Map) invokes its
parent constructor, which itself invokes deserializeInternal, which is
implemented on CraftBlockStateMeta to read the components and block
entity tag from the passed map.
Field initialization happens after the call to the super constructor,
meaning the current code overwrites the parsed internal data with the
EMPTY defaults.
This is prevented by moving the initialization into its own code block
that can null check the fields prior to defaulting their value to EMPTY.
The previous implementation would throw a command exception if the
CommandSourceStack had its bypassSelectorPermissions flag set to true,
which is the incorrect behaviour.
Instead, it should only throw an exception if the flag is set to false
and all its other checks "fail" too.
The brigadier command dispatcher is not capable of executing commands
that redirect more than one.
The exemplary alias 'minecraft:tp' may hence not redirect to 'tp' it
instead has to redirect to 'teleport' as 'tp' itself is merely a
redirect.
There is no need to rewrap vanilla goals when they're being reregistered,
this breaks some expectations around behavior outside of general
wasting of resources.
Resolves: #10743
Allows using the PluginLoader API without any of the other changes imposed by switching to a paper-plugin.yml.
Used by setting paper-plugin-loader in plugin.yml to the class name of your PluginLoader.
Also allows skipping the libraries field by setting paper-skip-libraries to true (by default both libraries and jars provided by the PluginLoader are added to the classpath).
The patch does not implement Vanilla forceUpgrade behavior.
Specifically, poi/entity conversion and regionfile recreation.
The Vanilla force upgrader is also no longer broken by CB, so the
bug fixes from this patch are not relevant anymore.
