Hi,

I have fully compiled and loaded your plugin on a 1.8.6 Spigot server. However, after the use of the /fp set or /fp multiset command, I get this error and results in no picture displayed on the item frames :

This line in the file Utils.java is the problem : "Channel channel = (Channel) field.get(netty);"

Have you a suggestion to solve this issue? I can test it too and send you a patch to add Spigot 1.8.6 support in your plugin if you want ;)

Here is the result after the use of the command : /fp multiset http://fc07.deviantart.net/fs70/f/2010/300/7/6/neko_girl_by_kaguyananbufan-d31m7re.jpg
