Follow this template except for feature requests. Use pastebin when providing /protocol dump and any relevant errors.

Make sure you've done the following:

  • You're using the latest build for your server version
  • This isn't an issue caused by another plugin
  • You've checked for duplicate issues
  • You didn't use /reload

Description and relevant errors:

Code:

    public void setSneaking( boolean sneakState, Player player ) {
        try {
            int id = (int) this.entityPlayer.getClass().getMethod( "getId" ).invoke( this.entityPlayer );
            ProtocolManager protocolManager = ProtocolLibrary.getProtocolManager();
            PacketContainer packetContainer = protocolManager.createPacket( PacketType.Play.Server.ENTITY_METADATA );
            packetContainer.getModifier().writeDefaults();
            packetContainer.getIntegers().write( 0, id );
            List<WrappedWatchableObject> wwoList = new ArrayList<>();
            byte bitmask = (byte) (sneakState ? 0x02 : 0x00);
            wwoList.add(new WrappedWatchableObject(0, bitmask));
            packetContainer.getWatchableCollectionModifier().write(0, wwoList);
            protocolManager.sendServerPacket( player, packetContainer );
        } catch ( Exception e ) {
            e.printStackTrace();
        }
    }

Have you tried this with a wrapped data watcher instead? Using the watchable collection should also work but it would help in debugging.
