Spigot has patched this issue inside MapIcon, meaning that we no longer need to maintain this patch; Spigots patch also fixes #668 in that it will verify the length of the array, as well as protect against a negative type value being fetched from the array. Only real change is that Spigots patch returns a MapIcon.Type.PLAYER, instead of the RED_MARKER as originally PR'd by Aikar.

Subject: [PATCH] MC-111699: Ignore Improper Anvil Item Name Packets
|
|
|
|
The client is improperly sending Item Name Packets to the server BEFORE
|
|
the click event. This causes the server to reset before the click event is processed
|
|
|
|
This breaks the ability to rename more than 1 item at a time.
|
|
|
|
