Honestly, I don't think anyone has any good suggestions. Upgrading from Java 7 to 8 was a GIANT undertaking for our shop, and I've heard 9 is not as easy as 8 which wasn't easy anyway. For example, we had trouble with Oracle Coherence locking up on Java 8. You'd think - Oracle is Oracle right? Now, the Coherence team saved the day with an excellent fix - but the underlying problem was due to a Java 8 bug! Furthermore, this highlights the fact that "everybody else" has time to kick the tires a bit and submit bugs, and Oracle has time to make the fixes. I'm all for the speeded up pace, but I just don't think Oracle is capable of keeping up with their own pace, honestly. HOWEVER, if the license terms are not exorbitant, I think it would be fine to send a little cash towards Oracle, provided we get a good ROI. Given the quick turnaround for Coherence, that seems very possible. Will be interesting..

...Thanks for very informative and helpful article. <br /><br />I was trying to find out the impact of this release train on other frameworks (JSF/Spring/Hibernate etc.) we use. Also as an architect/developer, should I migrate my current default JDK based application to OpenJDK+Docker Image model? We have application server shared by multiple applications, and all of those are developed on Oracle JDK (Java 8). Application servers uses Oracle JDK as well.<br /><br />Considering OpenJDK being used as a reference for Java 7 onward, would it be safe to use OpenJDK for windows OS based local development, but keep using future Oracle LTS JDK for PROD servers?<br /><br />Any suggestions?

There were two reasons: firstly, the numbering scheme for Java is already part of the specification, so it would have required a formal specification change. Secondly, for better or worse many scripts parse the Java version so to change the numbering scheme would have caused a great deal of disruption.<br />The rapid obsolescence of JDK 9 is no bad thing in my opinion: as the first stab at Jigsaw it always was going to be one to throw away. The adoption of the new release cycle has been a bumpy time but it's settling down now.<br />With regard to the support lifetime, this really only applies to those downloading binaries from Oracle: everybody else on Linux distros will use the OpenJDK that's packaged with their OS. It will be supported, along with the rest of the system, for whatever support period that OS uses.

Each major release contained at least one big and complicated feature which either delayed the release for months or was itself pushed after delaying the release for a while to a later release. Project Jigsaw for example. <br /><br />I for one am happy with the change of the release model. Going through the additional material on the Oracle page I found a presentation outlining the future LTS model in some detail. <br />If I got the details correct, JDK 8 will be supported until 2025, 18.9LTS until 2017 and 21.9LTS until 2030. So there will be a considerable overlap of LTS releases. <br />What I am not sure about is who gets this support. The main release train will be the OpenJDK which is only supported until the next available release. The Oracle JDK however is the one with the extended support. I assume that this support has to be bought from Oracle.<br />The support documentation however does not list an end-date for public updates on the LTS release. Only the Short-term releases are listed.<br /><br />So Oracle finally wants to start making more money from Java. Only time will tell how this move is embraced by the company world.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-741750605858169835.post-35728379932902229962018-02-06T18:27:26.639+00:002018-02-06T18:27:26.639+00:00I like this one, LOL.I like this one, LOL.snidehttps://www.blogger.com/profile/01594345219544000251noreply@blogger.comtag:blogger.com,1999:blog-741750605858169835.post-28088279357323305622018-02-06T17:41:24.989+00:002018-02-06T17:41:24.989+00:00The version numbering is absurd.

Java 9 and Java 10 are these transient releases, but Java 11 is a real stable LTS release? That is going to cause lots of unnecessary confusion. The naming should communicate the LTS vs non-LTS distinction.

If you look at Oracle's public presentations on this they show no overlap for future releases. When JDK 11 is released there will no longer be any public Oracle JDK binaries. These will only be available to users with a commercial support contract. Free binaries will be the OpenJDK builds released under GPLv2 with CPE licence. For those, there is *no* LTS release.<br /><br />In future, to use Java for free and get security patches you will need to change JDK *every* six months.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-741750605858169835.post-9483881620369826602018-02-06T08:00:30.996+00:002018-02-06T08:00:30.996+00:00Six weeks or six months?Six weeks or six months?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-741750605858169835.post-78951286232023222522018-02-06T05:48:25.195+00:002018-02-06T05:48:25.195+00:004.

The Java 9 release should have been named Java 17.9 to communicate the change in release strategy.<br /><br />The release strategy wasn't determined until well after the naming for Java 9 had been settled on. Further the year.month notation has been rejected in favor of continuing with a linearly increasing major version number scheme. <br /><br />I think Stephen's point was that people/organizations that upgraded to Java 9 perhaps didn't realize how short of a TTL it had and with tooling dependencies it might not be easy to update to Java 10 in a few weeks and then again to Java 11. Basically people might had not realized what they were signing up for when the upgraded to Java 9. <br /><br />I agree though that most organizations will likely stay on the LTSs. Heck how many orgs are still running Java 6 or 7?

The Java 9 release should have been named Java 17.9 to communicate the change in release strategy.<br />2) LTS support windows should overlap. The idea that there is no planned public support overlap between one LTS release and its successor is crazy.<br /><br />But beyond that, Java moving to a release train model sounds fine. Colebourne writes this post as if everyone will be forced to upgrade every six months. The release train model is designed to cater to crowds that want a slower upgrade commitment and don't necessarily need the very latest and greatest features and crowds that want the latest & greatest features but are willing to commit to frequent upgrades.<br /><br />I imagine most Java users will stick with the LTS releases. A convenient analog would be most shops running Ubuntu servers just use LTS releases. But other shops will want the faster releases, and that's fine. Every shop will choose to do what serves them and their client/user base most effectively.Clayhttps://www.blogger.com/profile/05193609370237229562noreply@blogger.comtag:blogger.com,1999:blog-741750605858169835.post-2933796881837834602018-02-05T14:18:18.130+00:002018-02-05T14:18:18.130+00:00The support page is the only public confirmation o...The support page is the only public confirmation of plans, which show a 4 month overlap between LTS releases (support for 8 ends 4 months after 11 is released): http://www.oracle.com/technetwork/java/eol-135779.htmlStephen Colebournehttps://www.blogger.com/profile/01454237967846880639noreply@blogger.comtag:blogger.com,1999:blog-741750605858169835.post-81510870311666660862018-02-05T14:09:34.675+00:002018-02-05T14:09:34.675+00:00Am I correct in understanding that there will be n...Am I correct in understanding that there will be no overlap between the support periods for either Java 8 or Java 10 and Java 11?
