[DISCUSS] Moving for JDK8, this time for real!
All,
I've been working on moving our codebase and runtime-environment to Java 8, and since this is a much needed big change I want your feedback and blessings on:
https://github.com/apache/cloudstack/pull/1888
In order for this to work, I had to make changes in our veewee-based systemvmtemplate build scripts to install a third party opensource openjdk-8-jre distribution (xulu-8 is a openjdk-8 distribution from Azul, please review and advise wrt their terms of usage here: http://www.azul.com/products/zulu/zulu-terms-of-use/), since
Debian 7 (wheezy) repositories don't have openjdk-8-jre and installing openjdk-8-jre from testing/sid updates several system packages such as libc that I wanted to avoid. Accepting this change on master/4.10 would require us to have a new systemvmtemplate for 4.10+ releases.
With these changes, I've ran smoke tests across KVM, VMware and XenServer in the following PR and all of the tests are passing (ignoring known intermittent failures in vpc/rvr related tests).
Thoughts, feedback?
Regards.

Thank you all, the PR has been merged now.
As a note, developers please setup Jenv in your environment and make sure to install/setup both JDK7 and JDK8 to help you work on master and 4.9/previous branches:
http://www.jenv.be/
No additional build changes are required.
For deploying and testing CloudStack from master, a new systemvmtemplate will be required. Please see for urls:
http://docs.cloudstack.apache.org/projects/cloudstack-release-notes/en/4.10/upgrade/upgrade-4.9.html#update-system-vm-templates
Regards.

All,
Thank you for your feedback.
We've no outstanding objections to the PR, at the time of the 4.10 release we'll document the new requirements around JRE1.8 and new systemvmtemplate in our installation/upgrade notes.
I'll proceed with the merge later this week.
Regards.

Yes, I understood that your proposal didn't change the debian version, I
suggested that it should do, since when we do update the debian version we
have to test everything over again anyway.
That said, I won't oppose your proposal, I'm +1 of upgrading to jdk 1.8

I agree with Rohit about not making too many changes at once. I know we
both agree that we should be going to Jessie, but let's do it in phases.
Going to Java 8 is a big enough step for right now, lets stabilize that and
then we can look at updating the system vm template after.

Posted by Rohit Yadav <ro...@shapeblue.com>.
Erik,
The PR I've proposed does not change the base Debian distro, it's still Debian 7 (wheezy) and not Jessie. I would like to avoid making too many changes in the same PR, especially moving to Jessie which won't be straight forward as it would introduce several changes, major package version changes, systemd usage etc.
What I'm proposing is simple -- moving to jdk8 for building CloudStack (this works flawlessly now), and using jre-8 on systemvm template.
Regards.

Wheezy has roughly 1 year left (until May 2018) before it is EOL.
Since 4.10 is not LTS and the fact that both Java8 and Debian Jessie
could have hard to find issues I would suggest that you update the
systemvm now, and work through bugs and quirks throught the 4.10.x
version.
I believe there are other changes, like strongswan, as well that could
make 4.10 a potentially unstable version?
