this discussion comes up about every 6 months, if you research the
mailing list archive you will get a lot of insight. check both the dev
and user mailing lists. Why not find open source that does what you want
there a few out there, like hibernate? it would seem to be a lot less
effort.

Yes, permgen space needs to be increased with this.
Sorry, I mis-understood your objection as a performance related to speed of the
newInstance() vs more classes.

The facade doesn't instantiate more objects than current, but the
class hierarchy is taller. (ie. when GenericValue.makeValue()
currently instantiates a GenericValue(), that factory would then
instantiate a class based on the entity name, that derives from
GenericValue()).
A class based on GenericValue(even one generated dynamically at
runtime, into a custom classloader), is still a class. Said class is
not loaded on the heap. It's bytecode is placed into permgen. More
classes would increase permgen pressure.
