Subject: [PATCH] Fix possible StackOverflowError for some dispenses
|
|
|
|
For saddles, carpets, horse armor, and chests for horse-likes
|
|
a BlockDispenseEvent handler that always mutated the item without
|
|
changing the type would result in a SO error because when it went
|
|
to find the replacement dispense behavior (since the item "changed")
|
|
it didn't properly handle if the replacement was the same instance
|
|
of dispense behavior.
|
|
|
|
Additionally equippable mob heads, wither skulls, and carved pumpkins
|
|
are subject to the same possible error.
