Comment (by karsten):

 So, I just tried out what happens if we ship the jars that we depend on in
 our descriptor.jar: even if the application using our descriptor.jar
 provides different versions of those dependent jars by itself, it will get
 what comes with our jar.  For example, if we ship a terribly old
 libcommons-codec, an application using our jar won't be able to use a
 recent enough version of libcommons-codec.  To state this differently,
 we'd be forced to update the libcommons-codec in descriptor.jar even if
 nothing relevant changes for us, just to ensure that applications using us
 can use the latest and greatest.  That's a dependency I'd rather not want
 to create.  I'm attaching a tarball with a small example.  Please read the
 Java code and Ant file and run the app.
