> I've attached a Document based on a hashtable and a performance test case. It performs
better in most cases (all but enumeration by my measurement), but likely uses a larger memory
footprint. The Document testcase will fail since it accesses the "fields" variable directly
and gets confused when it's not the list it expected it to be. 
> If nothing else we would be interested in at least being able to extend Document, which
is currently declared final. (Anyone know the performance gains on declaring a class final?)
Currently we have to maintain a copy of lucene which has methods and classes definalized and
overriden. 
> There are other classes as well that could be declared non-final (Fieldable comes to
mind) since it's possible to make changes for project specific situations in those aswell
but that's off-topic.
