A couple of points: - OpenJDK and Oracle's JDK have been nearly identical for quite some time, and they are identical as of this week. So whatever differences once were between Oracle/Sun JDK and OpenJDK, OpenJDK now is Oracle JDK. (https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later https://blogs.oracle.com/java-platform-group/oracle-jdk-rele...) - Enterprises have had to upgrade a JDK every six months for many years, now. But whereas JDK versions used to be named 8, 8u20, 8u40 etc., they are now named 10, 11, 12 etc.. In the past, JDK releases were also not supported more than six months. Some are under the impression that each of those is a major version; this is false. In order to make upgrades easier, Java no longer has major releases (Java 9 was the last), however, all releases now have their version number incremented ("Chrome versioning", if you like). To make this possible, the restrictions of what changes can be done with each 6-month release, so that the transition between, say, 12 and 11 is not quite the same as between 8u20 and 8u40, but it is also not at all like that between 7 and 8 or 8 and 9 (and closer to the former than to the latter). In addition, companies that don't want updates but only security fixes can purchase support from Oracle.
