The java.text.CollationElementIterator.reset() method does not work correctly.
This method throws NullPointerException when string under iteration is empty.

Here is the test demonstrating the bug:

-----------------TestA.java------------------------
import java.text.*;

public class TestA {
    public static void main (String args[]){
      RuleBasedCollator rbc = null;
      try {
        rbc = new RuleBasedCollator("< a < b");
      } catch (ParseException e) {
         System.out.println("Unexpected ParseException: "+e);
      }
      CollationElementIterator iterator =
            rbc.getCollationElementIterator("");
      iterator.reset();
      if (iterator.next() == iterator.NULLORDER) System.out.println("Ok");
    }
}
---------Output from the test in JDK1.1.6---------------------
java.lang.NullPointerException
        at java.text.CollationElementIterator.reset(CollationElementIterator.java:125)
        at TestA.main(TestA.java:13)

---------Output from the test in JDK1.1.5---------------------
Ok
--------------------------------------------------------------
