Yes, it keeps you of the street. KopiSusu 1.9b4 does implement references
to classes that are not on the command line. In that case, it tries to
load the source file from the class-path.

So, "ksusu -classpath . A.java" would also load B.java if A.java refers to
B.

About the problem that you still have when both A.java and B.java are
given on the command line, you would need to post some source code. From
the stack trace, it doesn't look like a class lookup problem, but
something else. I don't think KopiSusu will give the same exception, for
the simple reason that in the method that generated the ClassCastException
in your stack trace, KopiSusu first checks with 'instanceof'.
