It's worth pointing out that with Oracle's new Java licensing model whether something is free on charge depends on a number of things including how Oracle thinks it's being deployed. The Oracle JDK is indeed free of charge for developing aplications, but running that app using Oracle Java on a server as opposed to a desktop needs a paid license subscription & generates exposure to Oracle license audits. Many, many firms are now using OpenJDK and the like, and have policies against even downloading Oracle's version.
