While it wasn't really "broken" before, if plugins use NMS
(which they really should't be) and mess with entity management
themselves, and get it wrong, they could ultimately corrupt our
state expectations.
I've been unable to reproduce any issues locally, but these changes
are the result of me analyzing the code pretty deeply and seeing
about how to make it more durable to abnormal usage.
Any servers seeing oddities, please run with -Ddebug.entities=true
and send me any logs triggered.

5e3082c7 SPIGOT-4230: Improve legacy block types
This enables us a fast reference to the entities current chunk instead
of having to look it up by hashmap lookups.
We also store counts by type to further enable other performance optimizations in later patches.
At the time this was re-added, there was concern around how the JIT
would handle the system property that enabled it.
This shouldn't be a problem, and as such we no longer need to block
access to it.
The Vanilla Method Profiler will not provide much to most users however
there is no harm in providing it as an option. For most users, the
recommended and supported method for determining performance issues with
Paper will continue to be Timings.
This simply provides the base API to create the objects. Further commits will come that adds
adds usage of this API to existing GameProfile based API's, as well as new API's.
Improves performance by keying every chunk thats part of a structure to a hashmap
instead of only the first one.
This allows us to avoid iterating the entire structures value set to see
if a block position is inside of a structure.
This should have pretty decent performance improvement to any standard world
that has been around for a whilewith lots of structures due to ineffeciencies
in how MC stores structures (even unloaded chunks has structured data loaded)
FixesPaperMC/Paper#883 same issue as MinecraftForge/MinecraftForge#4386
A more detailed anaylsis of what is probably going on, courtesy of
@bs2609 and the MCForge Issue Tracker is:
When a chunk is unloaded, the entities and tile entities it contains are
marked for removal. The actual removal (from the world) occurs later,
when the world ticks its entities.
Conversely, when a chunk is loaded, it generally adds its entities to
the world promptly, without queuing.
Here's the normal sequence of events:
Chunk unloaded
Old entities removed
Chunk loaded
New entities added
However, what can happen:
Chunk unloaded
Chunk loaded
New entities added
Old entities removed
This occurs when an unloaded chunk is reloaded before its corresponding
entities have been removed.
