I won't have time to write any code in the next two weeks but I'll try
to put together an initial patch soon after that.

That's good to hear. Another example of something that would require API
changes is moving from static utility methods to instances. For example,
instead of:

  BeanUtils.copy(from, to); // I'm making this up

You might use

  BeanCopier bc = BeanCopier.create(fromClass, toClass);
  // time passes...
  bc.copy(from, to);

In most frameworks, the types of bean manipulations you will want to do
can be determined ahead of time. By holding direct references to the
relevant BeanCopier and other similar objects you can avoid a
synchronized cache lookup each time you need to do a copy.
