Block.getBiome returning strange result

I'm working on a plugin that randomly gets a block in a loaded chunk, and places snow on the top block, if it is one of the snow boimes.

Now, the first two parts work without a hitch. I can get the highest block, and I can place snow on it, but for whatever reason, if I try to check if the block is of the correct biome, the getBiome() method always returns Biome.FOREST

(e.g.)
if ( snowTest.getBiome() != Biome.FOREST ){
System.out.println("not forest");
} //this never prints anything, regardless of biome composition.

I'm not quite sure what could be causing this, as the world that I am testing the plugin on has a good diversity of biomes, and nothing else seems to be going wrong.

If anyone has any ideas as to the cause of this, I would appreciate hearing them.

 

Update to the newest version of craftbukkit, where they fixed it.

Ah, so it does. Thank you sir.

@narrowtux
Or not. It would seem that it is still doing the exact same thing.

What build was supposed to have fixed this precisely?
