Subject: [PATCH] Fix NPE on null loc for EntityTeleportEvent
|
|
|
|
EntityTeleportEvent#setTo is marked as nullable and so is the
|
|
getTo method. This fixes the handling of a null "to" location
|
|
by treating it the same as the event being cancelled. This is
|
|
already existing behavior for the EntityPortalEvent (which
|
|
extends EntityTeleportEvent).
