Cannot spawn Monster

I get

Code:

00:25:07 [ALLVARLIG] java.lang.InstantiationException

when I try to spawn Monsters (the creature Monster).
Anyone else who experience this?

It used to work with earlier builds (using 1185 atm).

 

its on leaky bukkit already. hopefully its fixed soon...

 

@vildaberper
What is your code? Because I think that error was fixed with latest build.

 

Code:

world.spawnCreature(location, creaturetype);

 

@vildaberper
Got the same error : / Guess it is still a bug.

 

The monster mob got removed in 1.8 and up.

 

That's a bummer

 

Wow, really?
Monsters were really fun to play around with.

 

that sucks =\
