Hi,
as expected this is quite a bit easier to follow. Thanks!
As any heavy use of reflection is likely to hit cached data, then heavily optimizing might be ill-advised here.
A simpler optimization might be to check if the class has any superclass or interfaces whatsoever first, since if not then publicFields == privateGetDeclaredField(true). This might reduce number of LinkedHashSets created for many trivial class hierarchies significantly for only a nominal increase in code complexity, and actually reduce the retained set a bit.
I am resisting the temptation to do that right now, i threw away a highly optimal implementation, i liked it, but you might not :-) An intermediate solution is to create a pre-sized Field[][] and not be as smart about that allocation. Mandy is gonna take a careful look next week. Paul.
