Something like this - and it is the same on both Apple JDK 5, Apple 
preview JDK 6 and SoyLatte (latest stable version). I also tried with 
something I compiled on Linux with JDK 6 - the same problem:

public final void mUnitDecimalLiteral()   throws 
java.lang.ArithmeticException;
    Signature: ()V

    Code:
     Stack=1, Locals=2, Args_size=1
     0:    goto    6
     3:    astore_1
     4:    aload_1
     5:    athrow
     6:    return
    Exception table:
     from   to  target type
       3     4     3   any
    StackMapTable: number_of_entries = 2
     frame_type = 67 /* same_locals_1_stack_item */
       stack = [ class java/lang/Throwable ]
     frame_type = 2 /* same */

    Exceptions:
     throws java.lang.ArithmeticException
  }


Cheers
