java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

1. Steps to reproduce
   a) Start the application, main class is ClippingBug. The JTable should
      fit the columns to display all the data.
   b) Select the "Print" button and print out the JTable. The text is clipped
      at the end of each table cell.

5. Relevant Information.
  Replacing the Strings ("MAMA MAMA ....") with lowercase makes the JTable
  print correctly.

  The printing code is taken unchanged from the Java tutorial:
