I note that you make no effort to evaluate my suggestion against yours for 
their relative merits.

You can use the existing type that has no no-arg constructor by using a 
builder inside a factory method.  No weird reflection needed - just a builder 
that knows how to construct the target object.

Since the builder is a *new* type, your comment that it doesn't have this or 
that is ridiculous.  You create the builder with a no-arg constructor and 
build what you need, returning an instance of the target type to the factory 
method.

How about you speak to that suggestion, hm?
