Defective skeleton has crashed my server!

I just recently downgraded to 1.4.7 and went on my server. I was walking around my main world, and I found two zombies. I started punching them and realized I wasn't going to kill them that way. I itemspawned a netherstar and enchanted it with thorns 32000. I put it on my head with /hat. The zombies punched me and died. Then, I got shot by a skeleton, so I decided to go into godmode. Before I could do this, my server had a lagout. On checking the crash report, it said that the server crash was because of a negative arrow velocity. I then restarted my server, killed the skeleton, and moved to a non-mobs dimension. Does anyone else have this problem, what may have caused it, might it happen again, and will it be fixed with the next update?

 

You "down-graded" to 1.4.7, there is no 1.5 Jenkins build for CB. So you either did it yourself, in that case we can't help you. Or you used Vanilla, then we can't help you either.

Theres 1.5 development builds out, they came out around 2:30 EST today.

 

I mean that I downgraded my client to get on my server. This happened before the 1.5 dev builds.

 

My bad, I wasn't aware of the release.

 

my guess is that an enchantment level that high is unstable.
