Strange. Read the dissection at Groklaw and you get a totally different perspective.
The general view there is that this is largely about whether or not Google need a licence to use the JAVA library API, so this largely rests on whether or not an API can be covered by "copyright" as a creative work. Just because an ex-SUN engineer thinks that Google DO need to acquire a licence is entirely irrelevant: he is not a lawyer and probably doesn't know what he is talking about. The context of that statement is likely to be risk aversion and playing "fair" to his prior employer.
Most of the examples of supposed "copying" are debatable, although not necessarily without merit.
