I think your lyrical rejoinder is a bit overstretched.  Sometimes=20
caching is good, sometimes it isn't.  In this case we are talking about=20
caching a small number or small items, which may be a performance win. =20

Notice that Alex said he would do some testing to see if this is=20
worthwhile.  It may not be.  We've been reducing the amount of explicit=20
caching in WM as JVMs have become much better at doing this for us. =20
It's difficult to predict when you will see a payoff without testing.

In this case the cache could just be a static map inside of the factory=20
class.  This optional overhead would be minimal and not interfere with=20
Servlet reloading in any way.
