FreeBSD Port: Extraneous class files?

[Peter Thoenen <eol1@xxxxxxxxx>]

So I have the port working and cleaning it up before I submit for
approval.  Not a java guy though by any means and using another java
port as a template for building games/ftjava.

On every FBSD java port I have looked at, the application is started:

exec java -cp ${CLASSPATH} a.b.c "${@}"  WHERE ${CLASSPATH} equals all
the required jar's.

In SFBOL though (from the included bat and ftjava linux documentation)
only a subset of these classes are listed though. 

Example: java -cp .:xerces.jar:activation.jar:mail.jar:pop3.jar
ftjava.gui.FTJava

Are all the other classes (imap.jar, log4j-1.2.7.jar,
xmlParserAPIs.jar, smtp.jar, mailapi.jar, png.jar, and xercesImpl.jar)
extraneous or are only they referenced by the orginally named classes
via ./some_dep.jar (so not required to list)

Also, do I need a dynamic ${CLASSPATH} that adjusts based on
.FTJavaPrefs? (for example if the user chooses IMAP instead of POP3 in
preferences)
