Ah, you have struck upon a nerve, the knee kicks up.  If I were skilled 
at finding old threads in our mailing list (which I'm not) I would show 
you the discussion we'd be having on derby-dev about code sharing.

I will try to summarize, but I'm sure others will chime in:

    * Currently the network client and the embedded driver and the
      network server are all totally independent packages of code
      (except for some shared constants)
    * We have had numerous discussions about enabling more code sharing,
      but it's trickier than you might think
    * I think we are coalescing on making it a goal to incrementally
      share more and more code. Two major areas: sharing the network
      code between the embedded client and the network server, and
      sharing the driver code between the embedded and network drivers. 
      Other areas include utility services that span these areas.
    * Your participation in this effort would be most appreciated.  So
      far we haven't made much progress mostly because of lack of
      resources (and also a lot of back and forth debate about exactly
      how to do it).
