Thanks!

Putting code in packages fixed the problem.

Now is the real question: what is the best approach to figure out this kind of
problems? I ran this example before, and this saved me from nervous breakdown
and jumping out of window. Slowly, by trial and error, I could trace the
problem back to the installation of JCE. Another route was to decompile
sun.security package and figure out debug flag values. I could not find any
references related to this problem on Sun site, including java developer
connection.
