+Subject: [PATCH] Remove CraftItemStack#setAmount null assignment
+
+This creates a problem with Paper's item serialization
+api where deserialized items, which are internally
+created as a CraftItemStack, will be completely lost if
+#setAmount(0) is invoked (since the underlying handle
+is set to null), while a regular Bukkit ItemStack
+simply sets the amount field to zero, retaining the
+item's data.
+
+Vanilla treats items with zero amounts the same as items
+with less than zero amounts, so this code doesn't create
+a problem with operations on the vanilla ItemStack.
