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] Fix "Not a string" Map Conversion spam
|
|
|
|
The maps did convert successfully, but had noisy logs due to Spigot
|
|
implementing this logic incorrectly.
|
|
|
|
This stops the spam by converting the old format to new before
|
|
requesting the world.
|
|
|
|
Track spigot issue to see when fixed: https://hub.spigotmc.org/jira/browse/SPIGOT-6181
