      Note that:
      - The issue does not occur with Firefox (40.0.3) on the same Mac
      - It does not occur on another Mac with the same java/browser configuration
      - It does not occur on Windows (With Firefox or Internet Explorer)
      - Cleaning the java cache make the error to occur later in the applet usage, but does not prevent it from occurring.

      Googling on this error show several reports of a very similar issue, but no real solution to this problem.
      The SunToolkit.java should handle this NPE with

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Just start the applet, and click around.
      If the Java Console is set to popup, clicking in the console may cause the issue as well.


      REPRODUCIBILITY :
      This bug can be reproduced always.
