You don't get that with Java 8 either, unless you are willing to pay for it. In that case, what's the difference between paying Oracle for support for Java 8 and newer releases?
It means having a service that you can contact with questions about the platform. For example, if you're having a weird GC problem you can pay Red Hat $300/hr to have a presumed expert (ideally a committer to OpenJDK) look at it with you and help you solve it. There may also be variants of this where you "subscribe" and get a certain number of support hours.
I'm curious if there is really a strong need for this service. What kinds of problems is a company solving and at what scale, that they need to have dedicated support with the language?
