KeyPairGenerator is one of the classes that were born broken when Sun
wrote them (MessageDigest suffers from a similar brain damage). I
think the point is that either (a) service providers write their own
`initialize' method when they extend the class, or (b) they implement
KeyPairGeneratorSpi and the getInstance method returns an "adapter"
class. See DummyKeyPairGenerator.
Throwing UnsupportedOperationException in this case sounds like a
better behavior. This is probably a case where it pays to emulate
Sun's behavior, but I don't think this will cause problems, since
service providers should extend KeyPairGeneratorSpi.
