It only happens on a server and it repeatedly kicks you until the entity is despawned and the console only outputs that.

updated title
Confirmed, just installed 1.4.6pre to try out the fireworks, instant crash upon firing them.
This obviously needs fixing since it's one of the features announced for 1.4.6.
I'm not sure what the title implys but this firework was created with gunpowder/paper.
Crashes with "INFO java.lang.NullPointerException".
The server I'm on has been down for just about 2 days now because of this.
Still shows up in the server list, but trying to connect either gives a communication error or End of Stream.
No idea what the server's saying since I don't own it.

"Minor" is the only possible priority in this bug tracker.
When I try to lunch fireworks - server (1.4.6 with diablo-jdk1.6) kicks me out. And I can't connect anymore.
I updated java to openjdk6, but still cant connect, see the log:

Can anyone else confirm that this only happens under the following circumstances:
End of Stream Crash with or without dispensers with plain Firework Rockets.
End of Stream Crash WITH Dispensers and any color Small Ball fireworks (no trails/twinkle/etc.., just plain Small Ball).
All other firework scenarios with or without dispensers seem to work fine.
Can anyone else confirm that this only happens under the following circumstances:
Yes. While fireworks is lunched, I can't log in to server. This method works for me:
Eli: keep trying to log in over and over. Each log-in causes a little game time to pass, so after about 20 or so failures, the firework will despawn, and you will be able to get in.
So, there is a problem with fireworks in multiplayer.
But in single player all works fine, even with dispenser.
> "Minor" is the only possible priority in this bug tracker.
Well that's pretty dumb, you'd think at least mods would be able to promote severe issues like this to "major" or something.
Can you please attach the complete crash report ?
