I'd rather not decode the path component unless absolutely necessary.

Yes, the jcifs/smb/Handler.java has access to this. It might simply be
a matter of determining that the java.net.URL class identified a #ref
and tack it back on. Boy that would be nice.

A  program should be written to model the concepts of the task it
performs rather than the physical world or a process because this
maximizes  the  potential  for it to be applied to tasks that are
conceptually  similar and, more important, to tasks that have not
yet been conceived.
