IllegalAccessError When accesing a block

Hey,

Somehow I get a IllegalAccessError with this code:

Code:

Block ladder = world.getBlockAt(location.getBlockX(), y, location.getBlockZ());
blocks.add(mcBlock.fromBlock(ladder));//Error at this line
ladder.setTypeIdAndData(Material.LADDER.getId(), (byte)2, false);

mcBlock.java:

Code:

public static mcBlock fromBlock(Block block){
           return new mcBlock(block.getWorld(), block.getTypeId(), block.getData(), block.getX(), block.getY(), block.getZ());
}

Tried this using the bukkit scheduler, but it makes no difference.

bump?

Use try/catch and print the stack trace?

 

There you go:

 

Ugh.. Lemme think

Try putting the fromBlock thingy in the same class. Then it should work for some reason
