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] Remove some Streams usage in Entity Collision
|
|
|
|
While there is more down the collision system, remove some of the wrapping
|
|
Spliterator stuff as even this wrapper stream has shown up in profiling.
|
|
|
|
With other collision optimizations, we might also even avoid inner streams too.
