Describe the question
Currently I am using:
- Spigot:
This server is running CraftBukkit version git-Spigot-db6de12-18fbb24 (MC: 1.8.8) (Implementing API version 1.8.8-R0.1-SNAPSHOT)
- ProtocolLib: 4.5.0
- ProtocolLib API (Gradle): 4.5.0 with official repository
It loads properly but when I joined to the server, it prints some errors on my screen.
and I tried to decompile ProtocolLib and check if there is no com.comphenix.protocol.wrappers.WrappedAttributeModifier class defined. but I found it correctly.
Calls
// event is PacketEvent which is received as argument on "onPacketSending"
ArrayList<WrappedAttribute>(event.packet.attributeCollectionModifier.read(0))causes
