But it's also wrong. Is there any legal precedent establishing what the "GPL with classpath exception" even means? Does each build of the OpenJDK come with it's own license?
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?
