Breaking a Dragon Egg in Survival with a high Haste effect crashes the game

Though you can't break a dragon egg, it should teleport away. Was this on a server? (Re the internal server error message)

Sorry, i'm spanish and i don't know write correctly in english.
Chek it with a enchanted pickaxe in survival.
Minecraft crash when you did it.

I tried hitting one with an Efficiency 1 Unbreaking 1 pickaxe and it teleported as expected.

Are you playing on a server or singleplayer?

In singleplayer.
Enchant a pickage with TooManyItems 1.4.2
Remember enchant all to 10.
Efficienty 10
Unbreaking 10
Silk Touch 10
...

Can't reproduce, but a few things:

1. If you're using any mod of any sort (this includes TooManyItems, Optifine, whatever) then any bug reports you submit to us are invalid. The bugs are very likely introduced with the mod, and not in vanilla. Please try in vanilla before submitting reports.
2. If you get a crash, we need to see the crash! We can't help you without it.

It works if you have a very extreme haste effect

for me, it was 9001 😃

Can confirm the crash.

Fixed by capping Haste at Level 255.
