Google adopted Apache Harmony for Android - as you might guess, Harmony also had an Apache license. You're right, the law suit has dragged longer, but Apache Harmony's tussle with the official JDK predates Oracle's purchase of Sun. Oracle inherited the fight and broadened it after Android was already a success. The whole Harmony TCK situation was a clusterfuck, because Sun was ostensibly for Free Software/ Open-Source, but a certified, Apache-licensed Java implementation would have killed the official JDK. Harmony was donated to the ASF by IBM - Sun's erstwhile rival. As an outsider, that era of Sun vs. IBM proxy wars was...interesting to follow. I had a chuckle when I learned that the "Eclipse" IDE was named to throw shade at Sun, and it was from a salty Sun CEO/employee.
