This patch does not appear to be doing anything useful, and may hide errors. Currently, the save logic does not run through this path either so it did not do anything. Additionally, properly implement support for handling RegionFileSizeException in Moonrise.

Subject: [PATCH] Improve CraftEntity and CraftPlayer equals and hashCode
|
|
|
|
Make sure the hash code does not change and also remove outdated
|
|
equals logic from CraftPlayer. Long-term, the override there should
|
|
be entirely removed, but this is good enough for now.
|
|
|
|
Replacing some getHandle method calls with direct field access will
|
|
also reduce overhead from casts that the overridden methods come with,
|
|
at least until those are changed later on as well.
