Cast a Block to Furnace (CraftBukkit)

(May not good english)
Like the title sais, i want to cast a Block to a Furnace.
But this doesnt is working .
First the code:

Code:java

 
//furnacesSmelt is a ArrayList with Locations from Furnaces
//this is standing in a while-Loop
Furnace f = (Furnace)furnacesSmelt.get(i).getBlock.getState();
 

But it throws a exception:
org.bukkit.craftbukkit.v1_7_R1.block.CraftBlockState cannot be cast to org.bukkit.blocks.Furnace
I am working with craftbukkit for editing Entitys and such stuff.
The Problem is: I get CraftBlockState and not "normale" BlockState, which i think is strange?
So how can i cast a CraftBlock to Furnace / CraftFurnace. (I tried both)
Thx for help.

Could you maybe post all your imports?

 

From what I see, you're referencing the actual craftbukkit jar, and not the api, which isn't really necessary unless you're planning on sending packets and things like that. Try reorganizing your imports and choose the ones that you need (No clue what IDE you're using, but usually you can see the package name)

 

Löwenpower Is your block even a furnace? (print the Block's getType().name() to be 100% sure)

 

Perhaps try

Code:java

//Assuming This is on Interact Event....
Block b = event.getClickedBlock();
if(b instanceof Furnace){
//TODO Do stuff if furnace
System.out.printf("This is a furnace");
}
else{
//TODO DO stuff if not furnace
System.out.printf("The furnace was a lie");
}
