[jcifs] Important New SMB URL Semantics

[Michael B. Allen]

I  just  converted  URL  handling  in  jCIFS  to use java.net.URL entirely.
However   the   java.net.URL  semantics  are  a  little  different  in  one
significant  way.  Previously  you could compose an SmbFile from parent and
child paths like: 

  smb://server/share/path + to/file.txt

which used to give you:

  smb://server/share/path/to/file.txt

but with java.net.URL doing all URL handling this now gives you:

  smb://server/share/to/file.txt

This  is  because  there  was  no  '/'  at  the  end of the first component
indicating it's a directory. If you just always put a '/' after directories
everything works: 

  smb://server/share/path/ + to/file.txt

This should confuse a few people but technically it's correct. But we could
override  the  default parsing and relax the semantics a litte if it's real
problem.

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 importantly to tasks that have not
yet been conceived.
