In order to check if a chunk exists, the RegionFile lock
(if the RegionFile is opened) will be acquired. However,
the RegionFile may be performing I/O operations, in which
case will stall the acquire operation.
To ensure that threads scheduling loads do not incur a stall,
we can avoid this check entirely - the RegionFile I/O
thread(s) will eventually perform the exist check itself.
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).
