Solved Ambiguous instanceof

I am trying to override an internal NMS check by changing the type of a field (entityplayer.activeContainer) from the usual minecraft type (Container~ that extends Container) to my own type (that extends Container aswell).

Every time I get the NMS instance of the player and check the type of it and perform the same check as done in the NMS code I want to override it returns false (thus code should not be executed). I still see that the code is executed, does anyone know why this could be and how it could be fixed?

NMS check (yes, someone forgot a second " and the code is messed up that is fixed in the craftbukkit.jar though): https://github.com/Bukkit/mc-dev/blob/master/net/minecraft/server/PlayerConnection.java#L843

Code:java

this.player.activeContainer instanceof ContainerAnvil

Should return false (checked by my plugin) seems to return true though....

 

Bump

Nvm this seems to be absolutely client-sided sadly.
