both fix for the NPE and for the ArrayIndexOutOfBundsException issue.

> The methods of object constructed by java.text.Bidi(AttributedCharacterIterator) throws
unexpected NPE on harmony classes while RI return correct value. For example, getRunLimit(1):
> ===================== test.java ====================
> import java.text.*; 
> public class test { 
>     public static void main (String[] args) {
>         AttributedString paragraph = new AttributedString("text");
>         Bidi bidi = new Bidi(paragraph.getIterator());
>         try {
>             System.out.println("getRunLimit(1) = " + bidi.getRunLimit(1) + "\npassed!");
>         } catch (Exception e) {
>             e.printStackTrace();
>             System.out.println("failed");
>         }
>     }
> }
