      A DESCRIPTION OF THE PROBLEM :
      This happens on the new J2SE SDK 1.4.2 release, running the tool from a DOS console in XP.

      - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
      APPLETVIEWER menu option: Applet>RELOAD - CAUSES TOOL TO CLOSE AND HANG at the dos prompt.
      The process exists, but it won't return to prompt, it just hangs.
      I've pasted below (Steps to Reproduce) one of the rare cases when i did get an exception - actual first time - after a long hang (minutes).
      = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =


      I'm also running the 1.4.1. SDK without any problems.

      May be relevant for reproduction:
      - - - - - - - - - - - - - - - - -
      I've recently uninstalled the 1.4.1_02(b03?) JRE - prior to installing JRE 1.4.2.

      I've manually deleted any folders left after uninstallation and reboot - there was one file in a folder - just the name that? I think it did say applet somewhere. It was just a single file in a folder left after uninstallation of 1.4.1 (b03?) JRE (is this relevant?)

      1.4.1_02-b06 Appletviewer runs fine with the SDK's personal JRE on a different folder.

      My environment variables at the prompt below:

      D:\j2sdk1.4.2>echo %PATH%
      C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;D:\AliasWavefront\Maya 4.5 Personal Learning Edition\bin;D:\j2sdk1.4.2\bin;C:\WINDOWS;C:\WINDOWS\System32\Wbem;D:\AliasWavefront\Maya 4.5 Personal Learning Edition\bin;

      D:\j2sdk1.4.2>echo %CLASSPATH%
      %CLASSPATH%;.;D:\j2sdk1.4.2\lib\tools.jar;D:\j2sdk1.4.2;
