Hi, I'm unable to reproduce this. Could you please attach the crash report generated after experiencing this issue? You should be able to find it within the crash-reports folder in the directory containing the server jar.

Right, I'm familiar with this exploit. The issue is only present in servers running Spigot and its forks, and it's a result of an invalid namespace provided in the enchantment command. You're better off reporting it to those folks.
