For Java 11, "all that work" was really just to keep the options for the project open. Some components (like JAI library) throw lots of warnings into the logs that tend to concern users in a production environment. We really pushed hard to be able to run in Java 11 at all, and the sprint participants are to be thanked. We really felt the pressure because at the time the continued support for Java 8 was very much in doubt at the time.
I am not sure what it would take to make Java 11 the recommended one, it is not something my customers have requested. As a volunteer I have been working on replacing the JAI component in my own time, which for me is the largest technical risk. AdoptOpenJDK / Redhat / Ubuntu are all different distributions of the same OpenJDK project. The different distributions all have different polices around how long they support each release for. Oracle actually has two distributions going, commercial for long term support, and free for 4 month support. The key player here though is not Oracle, but RedHat. RedHat has committed to backporting security fixes for their customers. They have a "upstream first" policy so those fixes make it into OpenJDK. Once in OpenJDK it shows up in distributions like Ubuntu, AdoptOpenJDK and others ... so you should be able to figure out which version of OpenJDK you installed and check its release notes for security fixes. While I like to recommend AdoptOpenJDK (in part due to its installers for MacOS and Windows), many folks are running a linux distribution and thus have a supported distribution that way. Can I ask what platform you are running your compliance testing on? -- Jody Garnett On Thu, 2 Jan 2020 at 00:54, Paul Wittle <[email protected]> wrote: > Hi Jody, > > > > Thanks for getting back to me. > > > > I’ll give that a go although my colleagues had already tried that one for > a different application and had issues.
