[classlib][lang]compatibility: expected IndexOutOfBoundsException for  Character.codePointAt
--------------------------------------------------------------------------------------------

                 Key: HARMONY-1033
                 URL: http://issues.apache.org/jira/browse/HARMONY-1033
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Denis Kishenko


Specs 1.5
Methods throws 
  NullPointerException - if a is null. 
  IndexOutOfBoundsException - if offset or count is negative, or if offset + count is larger
than the length of the given array.

If first argument is null RI throws NPE only in the second test, it's strange, but we have
to follow.

public class bug9276 {

    public static void main (String[] args) {
    	try {    		
    		Character.codePointAt(null, 6, 4);
    		System.err.println("failed 1");
    	} catch (IndexOutOfBoundsException e) {
    		System.err.println("passed 1");
            e.printStackTrace();
    	} catch (Exception e) {
    		System.err.println("failed 1");
            e.printStackTrace();
    	}
    	try {    		
    		Character.codePointAt(null, 4, 6);
    		System.err.println("failed 2");
    	} catch (NullPointerException e) {
    		System.err.println("passed 2");
            e.printStackTrace();
    	} catch (Exception e) {
    		System.err.println("failed 2");
            e.printStackTrace();
    	}
    	try {    		
    		Character.codePointAt(null, 0, 0);
    		System.err.println("failed 3");
    	} catch (IndexOutOfBoundsException e) {
    		System.err.println("passed 3");
            e.printStackTrace();
    	} catch (Exception e) {
    		System.err.println("failed 3");
            e.printStackTrace();
    	}
  }   
    
}
