Upon further knowledge of the system, it is known that region files are closing properly, as well as this didn't help native memory use anyways. This patch also caused issues compiling on a newer JDK being able to release the jar to java 8 users.

Subject: [PATCH] Optimize sending packets to nearby locations (sounds/effects)
|
|
|
|
Instead of using the entire world or player list, use the distance
|
|
maps to only iterate players who are even seeing the chunk the packet
|
|
is originating from.
|
|
|
|
This will drastically cut down on packet sending cost for worlds with
|
|
lots of players in them.
