https://jira.spring.io/browse/SPR-11656 has a pretty good description of spring 3.2.13 support for Java 8 They did add support for Java 8 bytecode. I am only at 3.2.4 and have no problems but we are pretty explicit about wiring and do not use autowiring. In the end, we will all end up moving

All my code is compiled with Java 8. I have not had any problem since I moved my stuff to Java 8 with Spring 3 but I may just be lucky. I am not sure how much of a change to code or configurations is required to upgrade to Spring 4 so it may not be a big deal to do both upgrades in one rele

Sorry. You misunderstood my comment. I was noting that users who want to run ACS which requires Java 8 could also run applications that can not run on Java 8 (although I have never heard of an application that would not run with the Java 8 JRE) by running both jre7 and jre8. Of course once y

Ron, According to Spring's documentation, Spring 3 only supports running byte code compiled for 1.7 on a Java8 VM [1]. Spring 4 is the first release to support byte code compiled to 1.8 running on a Java8 VM. Our experience with CloudStack 4.5 and master on Java8 has been that it runs, but

Ron, Upon upgrade, we will start using features and runtime classes/methods introduced with Java8. Therefore, it will become mandatory upgrade from Java7 to Java8 when adopting the release with these changes. Thanks, -John > Regards, John Burwell john.burw...@shapeblue.com  www.shapeblue.c

It would seem that a major version would be appropriate. I am not sure why someone could not use both Java 8 and Java 7. I have Java 3 versions 6, 7, and 8 available on my Windows 7 PC. I would have thought that Linux would be at least that flexible. Is it really not possible to run Java 8 on U

All, Java8 is targeted for post 4.9. Oracle provides an official PPA for Java6, Java7, Java8, and Java9 [1] that supports Ubuntu 14.04. It is important to bear in mind that Java7 was EOL’ed on April 2015 [2]. In my opinion, the recent history of Java vulnerabilities dictates that we cannot a

It only means that we are dropping support for newer ACS versions. It most likely won't get into 4.9, which means 14.04 will be supported a few more weeks/months. We could mention in the 4.9 RN that for the next release (call it 5.0 because of the change?) will only be supported by $xyz distributi

I am in favor of Java 8, but it means we would drop Ubuntu 14.04 support. That would make life a bit easier though, since Ubuntu 16.04 has systemd and 14.04 still has sysvinit and that make packaging a problem. > Op 13 mei 2016 om 19:10 schreef Rohit Yadav : > > > All, > > > I've started som

I am not sure what you are using in Spring but I have been using Spring 3.x.x with Java 8 for some time. I can believe that Spring 4 is "better" than Spring 3 but you might see if you can separate these two technology upgrades just to keep it simple. There is enough in Java 8 to make a pretty b
