Able to Cast Block to Depreciated Diode but throws Block Cannot be cast to Repeater error if using Repeater.

Function Header: RepeaterHandler(PlayerInteractEvent e)

CODE WORKS:

Block RB = e.getClickedBlock();

if(RB.getType().equals(Material.REPEATER))
     Diode repeater = (Diode)RB.getState().getData();

CODE FAILS:

Block RB = e.getClickedBlock();

if(RB.getType().equals(Material.REPEATER))
    Repeater repeater = (Repeater)RB.getState().getData();
