I'm not sure how common knowledge this is, but Oracle is quietly going after any company of any significant size which uses Java in their software at all. It's not just the embedded stuff either; simply using Java in enterprise software is enough to bring them running with their team of lawyers threatening a lawsuit. These suits are being settled at large sums without raising any external indication that this is going on. It's not the big guys or the startups that have to worry, it's the mid-sized companies that know a long, protracted lawsuit with Oracle will not end well for them.
