John:

Well, at least it looks like they have the same swing packages now
(1.2 used to stick jfc elsewhere, making it impossible for anything
that used com.sun.swing.* to work in 1.2).

Off the top of my head, make sure you are using the 1.2 classes only. 
classes.zip doesn't exist anymore, it's replaced by the rt.jar found
in jre\lib.  There isn't much to go on in the error trace you
attached.

I'd make a "clean" dos box, set the classpath to use your classes
compiled in JBuilder, the jars for the jbcl and jgl stuff and only the
JDK classes from the 1.2 set.  Most often I see weirdness just because
some cross-references snuck in via the CLASSPATH.  Now, the mechanism
that JBuilder uses to build the classpath is in the docs, but working
clean still seems to isolate the problem faster.
