[8] Review request for 8005019 JTable passes row index instead of length when inserts selection interval

[Alexander Scherbatiy]

Hello,
Could you review the fix:
  bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8005019
  webrev: http://cr.openjdk.java.net/~alexsch/8005019/webrev.00

Fixed type in the modelSelection.insertIndexInterval() method call which 
requires length in the second argument instead of endModelIndex.

Thanks,
Alexandr.
