checked and found jvm.cfg is at D:\Program Files\Java\j2re1.4.1\lib\i386

changed i386 to i586, then showed correct version name: (build 1.4.1-beta-b10)

Verified with a new build of (jupdatexxx)_141-b13.exe Kumar gave me, the problem is gone. The update lib directory now has both i386 and i586 directories.
