Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable. It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Avoid Lazy Initialization for Enum Fields
|
|
|
|
This patch is meant to get rid of any instances of lazy initialization that Minecraft introduces for enums.
|
|
This has the possibility to create race condition issues, and generally don't make sense to be lazily done anyways.
