Requiring Java 8 during runtime
Hello, As you probably know oVirt Engine 4 will use WildFly 10, and that requires Java 8. The version of WildFly that we currently use is 8.2.1, and it can work with both Java 7 and Java 8. In order to ease the transition I'm about to merge the following patch, that will require Java 8 during runtime: core: Require Java 8 during runtime https://gerrit.ovirt.org/46872 The implication of this for you is that you must make sure that you have Java 8 installed in the machine where you run your the engine. Fedora 22 only supports Java 8, so that isn't a problem. EL6 supports both Java 7 and Java 8, so make sure that you have Java 8 installed: yum -y install java-1.8.0-openjdk-devel If you have objections please speak now, otherwise I will merge the patch tomorrow.

not strictly related question: are we going to raise language level as well? So we can start using JDK8 features like lambdas etc? M. ----- Original Message -----

Shortly after merging that patch I'll merge another one to raise the language level in the RESTAPI: restapi: Use Java 8 as source and target https://gerrit.ovirt.org/46288 Doing the same in other components is up to their maintainers. I think that should be done everywhere, except where the use of GWT doesn't allow to do it.

I think it's a really bad practice to have different modules in the same project with different language versions. For GWT it seems to be required, but for the rest of the backend, I think we should have one patch that moves the entire project in one go. We can have the various maintainers ack it to show their consent. On Mon, Oct 26, 2015 at 1:17 PM, Juan Hernández <jhernand@redhat.com> wrote:

I agree with Allon, there's no reason to have different version throughout the modules (again, not including GWT for obvious reasons), there is practically no harm I can think of in raising the version for all modules at once On Tue, Oct 27, 2015 at 10:36 AM, Allon Mureinik <amureini@redhat.com> wrote:

I have updated the patch to raise the level in all the projects except the ones that require Java 7 because of GWT: core: Use Java 8 as source and target https://gerrit.ovirt.org/46288 Please review.
