According to Oracle it's "obviously" indefensible. They don't say why though, and saying it doesn't make it true. Oracle really has a knack of coming off like a whiny 5 year old (but it's not FAIR) rather than arguing the actual law. Sure you put a lot of work into the Java libraries, Oracle. (Well, actually you didn't, Sun did). That doesn't mean it's protected by law. There are plenty of things that you can invest heavily in that aren't protected by law. Just because somebody "taps into your fan base" doesn't mean they violated copyright law. By that logic, anybody that creates any Java library that uses core Java APIs as input/output is also using the Java API unfairly.
