Google says it did clean room implementation but investigation uncovers that Google copied and pasted a lot of code to rush through development and there were strict guidelines set to remove the use of word "Java" from the source code repository which even delayed some of their launch So Google might have simply used Java's code without ever being able to source a license. So here the case is not merely copying API but source code too. If you read the case history, even Google's key employees knew this, they were worried and they did try to acquire the license till end but failed to do so, they proceed to move on with the project. (Disruption mindset? Will pay the fine if caught later?) Google surely underestimated who they were messing with.
