When I op a player to level 2 on minecraft_server_1.8.6 it works just fine. The player is able to run command "/gamemode 2", but not command "/stop". This is correct. But on bukkit or spigot 1.8.6 the player is able to run commands "/stop" "/ban" "/kick" while he is on level 2 in ops.json. I have tested this thorougly now. Anyone experienced the same?
