+# SpecialSource2 automatically maps methods to the name of synthetic methods that point to it in an attempt to

+# SpecialSource2 automatically maps the second method name to the name of the first method, in this case `a`.

+# LootEntryAbstract$Serializer also has another method with the same descriptor as serialize(), which Spigot calls
+# serializeCustom(). Of course ProGuard strips the names and since this method is the first time it's seen this
+# descriptor, it renamed that method also to `a`.
+#
+# This is allowed because the synthetic method for serialize() has a different descriptor, using Object as the second
