      ========================
      To reproduce bug:
      1- Compile and execute the TableExample4.java file that is distributed with the bundle under:
      ..jdk../demo/jfc/src/TableExampl4.java or the file I listed at the end of this text.
      2- Double click on a JTable cell and insert some Hebrew text
      3- Double click on a another cell and insert some Hebrew text
      4- Verify that inserting Hebrew Text causes NullPointerException to be thrown.
