Application does not run on different versions of the Solaris OS

[Al]

My application throws an exception on a Sun Solaris 5.6 machine. But
when I run
my application on an older version of the OS Sun Solaris 5.5 the
application is
happy.

I am using JDK 1.3 (or 1.6) and swing-1.0.2. On both platforms I
have the
same environment and class path. The only difference is the version
of the
Operating system.

Thanks

Al
