please add support for openjdk-8

[Nick Gaya]

Please add support for OpenJDK 8. I conjecture that this can be done by adding the relevant packages to the postinst script (see links).

1)
$ lsb_release -rd
Description: Ubuntu 14.04.5 LTS
Release: 14.04

2)
$ apt-cache policy ca-certificates-java
ca-certificates-java:
  Installed: 20130815ubuntu1
  Candidate: 20130815ubuntu1
  Version table:
 *** 20130815ubuntu1 0
        500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
        100 /var/lib/dpkg/status

This is the first Ubuntu bug report I have filed. Please excuse any bureaucratic errors I may have made.

Status changed to 'Confirmed' because the bug affects multiple users.

[Samuel Penn (y-sam-7)]

This is quite critical for us, and anyone else who has software with dependencies on Java 8, since that software no longer installs on 14.04 and there is no workaround. The change that caused the problem is actually in the openjdk package (which worked up until yesterday when the change was made):

https://launchpad.net/~openjdk-r/+archive/ubuntu/ppa/+sourcepub/8107440/+listing-archive-extra

[Jesse S. (j.stubbins)]

I echo the above statement. Virtually all of my company's applications now use Java 8 on 14.04, so this working is quite important.

Looks like the packages are rebuilding right now, so hopefully that resolves this issue.

We're also finding that we cannot install Java 8 on Trusty anymore. One other thing I noted is that the openjdk-8 package seems to have a 'Breaks: ' directive for older versions of ca-certificates-java, including this version.

This is a really serious issue for us, and this is not the first time Java support on Ubuntu LTS has broken in really bad ways that makes me wonder what sort of testing and validation these packages go through :/

[Matthias Klose (doko)]

this has nothing to do with the LTS. It's a PPA.

[Samuel Penn (y-sam-7)]

Sorry, simply saying it's invalid isn't very helpful, especially for a critical bug. How should the bug have been raised? What can we do to raise it in the right place?

I've already tried raising a bug against the openjdk-r PPA, but just get a message that openjdk-r isn't configured to receive bugs.

Looking at the openjdk-8 update which caused the problem, it's saying that it's been deleted, so does that mean that the change has been rolled back, and things should be working again? If so, thank you.

[stevenschlansker (stevenschlansker)]

Independent of the "Java is completely broken" issue, I do think the originally stated case of "ca-certificate-java should support openjdk-8" is still totally valid. Installing this package seems to bring in java 7 even when you already have 8 installed.

The current situation is pretty ridiculous. Java 7 is EOL and not useful to the majority of users of the most popular languages on the planet. Java 8 is only available via an unsupported PPA, and any attempt to get support (either here, or on the PPA, or via the request process to get Java 8 added to Trusty) has simply failed.

I hate being that guy whining on the bug tracker, but Ubuntu is really dropping the ball on this one. Just look at the request for an official Java 8 packaging: https://bugs.launchpad.net/trusty-backports/+bug/1368094 with 750 "+1"s.

The community is trying to work with Ubuntu to highlight this and get it fixed, but every attempt either gets ignored or closed as invalid...

[Nick Gaya (ngaya-ll)]

From what I can tell, the rationale for adding the "Breaks" directive in openjdk-8 was that with the current version of ca-certificates-java, users who do not use one of the enumerated JVMs will not have their cert store updated when this package gets updated, which is a security problem for those users.

It's true that openjdk-8 comes from a PPA, but since it appears trivial to add support (see links) I don't see why not.
