Hi,

One easy way to identify the classes that will be required is to launch
ImageJ (or your alternate application) from the command line with the
"-verbose" command line flag. E.g.:

   ./jre/bin/java -mx512m -verbose -cp ij.jar ij.ImageJ > out.txt

Perform all of the operations you plan to use within ImageJ, then quit
the program. Open up the out.txt file and strip out lines not starting
with "[Loaded ij." The remaining lines represent a list of classes that
were required at some point during the program execution, and should
probably be bundled with your smaller JAR.
