Paulex Yang commented on HARMONY-2063:
--------------------------------------

Tony, the second patch is applied at revision r with minor changes, I tidied it up to remove compiler warnings, and replaced the "if (obj != null && obj instanceof xxx)" with "if(obj instanceof xxx)", because the instanceof always false for null. Thank you for this enhancement, please verify the issue fully resolved as you expected.

> RI caches the value when calling hasNextShort() for following nextShort(), but harmony does not.
> Refer to testcase below,  which passed on RI but failed on Hamorny.
> Scanner fails for this test 
> public void testNextShort() { 
> Scanner scanner=new Scanner("123 123"); 
> assertFalse(scanner.hasNextShort(16) && scanner.nextShort()==123); 
> }
