Your setup must be different, because it apparently worked for you
with an empty CLASSPATH.  I couldn't run Jacks at all without setting
CLASSPATH to find libgcj-3.4.jar.  

Interestingly enough, this piece in _set_classpath in jacks.tcl omits
adding . to the CLASSPATH if it is empty:
    # If adddot is true, then append . to the CLASSPATH
    if {$CLASSPATH != "" && $adddot} {
        append CLASSPATH ${PATH_SEP}
        append CLASSPATH .
    }

Does an empty CLASSPATH have some special meaning?

Bye,
Ulrich
