Grief Prevention

Observed Behavior

There's some issue with GriefPrevention and taming wolves with the latest 1.21.5 update. Everytime a player in the server I'm on (and myself included) try to tame an untamed wolf, the server immediately crashes. I've deleted all the plugins and reinstalled one-by-one, and it seems to be caused by GriefPrevention specifically, but I'm not sure what exactly from the plugin caused this. Tamed wolves + breeding them do not cause this issue, only taming feral wolves. Hoping for advice or potential fix for this.

Expected Behavior

Previously before the 1.21.5 update, players are able to tame the wolves just fine without the server crashing.

Reproduction steps

Dunno if this helps, but this even happens in Creative Mode, and with server Operators too.

Make sure GriefPrevention plugin is installed (from scratch or pre-existing, ive tested both)
Spawn/Find an untamed wolf in the world
Get a Bone, use it to tame the wolf
Server crash

Plugin list

Running without GriefPrevention

I attempted running the server without GriefPrevention installed.
The problem does not occur when GriefPrevention is removed from the server.

Running with only GriefPrevention

I attempted running only GriefPrevention on the server.
The issue still occurs when GriefPrevention is the only plugin running.

Running on a fresh, clean server installation

I attempted testing for the issue on a new server.
The issue still occurs on a new server.

Using unmodified client

I attempted testing for the issue with the vanilla client.
The issue still occurs when using the vanilla client.

We appreciate you taking the time to fill out a bug report!

I searched for similar issues before submitting this bug report.

The only thing I can think of that might be causing an issue would be

GriefPrevention/src/main/java/me/ryanhamshire/GriefPrevention/PlayerEventHandler.java

Lines 1237 to 1246 in 47cb363

    
           else  //world repair code for a now-fixed GP bug //TODO: necessary anymore? 
        
           { 
        
               //ensure this entity can be tamed by players 
        
               tameable.setOwner(null); 
        
               if (tameable instanceof InventoryHolder) 
        
               { 
        
                   InventoryHolder holder = (InventoryHolder) tameable; 
        
                   holder.getInventory().clear(); 
        
               } 
        
           }

This probably is a Spigot bug.

@Jikoo

@Jikoo Do you have any suggestions on how to fix this perhaps ? But just for clarification, are you implying that there's something in the new Spigot update that may be clashing with GriefPrevention ?

This is likely a bug in Spigot, not in GP. It is probably triggered by GriefPrevention setting the owner of the wolf to null, which is how the Bukkit API allows plugins to remove ownership. If that is the case there's nothing GP can do - it's an issue with the implementation of the API.

Would need to create a minimal reproduction plugin to be entirely confident, but as it stands, you'll note that the stack trace doesn't directly implicate GP - the problem occurs later when the entity's datafixer runs. The way Spigot handles ownership removal is probably not correct any more due to changes in Minecraft internals.

	else //world repair code for a now-fixed GP bug //TODO: necessary anymore?
	{
	//ensure this entity can be tamed by players
	tameable.setOwner(null);
	if (tameable instanceof InventoryHolder)
	{
	InventoryHolder holder = (InventoryHolder) tameable;
	holder.getInventory().clear();
	}
	}
