Erick Erickson resolved LUCENE-778.
-----------------------------------

    Resolution: Won't Fix

SPRING_CLEANING_2013 We can reopen if necessary. Think this code has been extensively re-worked
anyway.

> In our application, we have some kind of generic API that is handling how we are using
Lucene. The different other applications are using this API with different semantics, and
are using the Lucene fields quite differently. We wrote some usefull functions to do this
mapping. Today, as the Document class cannot be overriden, we are obliged to make a document
wrapper by application, ie some MyAppDocument and MyOtherAppDocument which have a property
holding a real Lucene Document. Then, when MyApp or MyOtherApp want to use our generic lucene
API, we have to "get out" the Lucene document, ie do some genericLuceneAPI.writeDoc(myAppDoc.getLuceneDocument()).
This work fine, but it becomes quite tricky to use the other function of our generic API which
is genericLuceneAPI.writeDocs(Collection<Document> docs).
> I don't know the rational behind making final Document, but removing it will allow more
object-oriented code.
