Latest response

OpenJDK 11 went GA 25 Sept 2018.
I am looking repository path on which OpenJDK 11 rpms are hosted if java 11 is available on RedHat Repository.

After attaching to the streams with subscription manger, I couldn't find the openjdk 11 rpms from rhel-7-server-rpms repo

Hi Sarfaraz,

Please read the Red Hat OpenJDK 11 Advice - it says : Red Hat is planning to release ... "as soon as possible". :)

Regards,
Christian

Hi Sarfaraz,

You are a little bit early ... OpenJDK 11 is still in "Red Hat testing mode" and hence as of today not available in the repositories.
Once OpenJDK 11 is being made available, I think we'll see an official announcement, and a matching Knowledgebase article. :)

Regards,
Christian

thank you for the update. Can you please let us know the dates as to when can OpenJDK 11 will be part of repository?

You're welcome, Sarfaraz ! :) Unfortunately I can't tell you the exact availability date because I'm not a Red Hat employee, but I think as OpenJDK is a popular application, it won't take too long until it gets pushed to the repositories. Mainly it depends on stability - which means : "It's ready when it's ready".

Regards,
Christian

Thanks Christian. Can you give me the reference of a person who can confirm the tentative dates for openjdk 11 rpm in the repo?

No Sarfaraz, I can't ... and even if I could name a person, you wouldn't be lucky, because the Red Hat developers generally don't provide information about when software versions get released - sorry. :)

Regards,
Christian

Hi Safaraz,

QA in general take at least a month or so, if faster it would mean that the older versions contain a generic bug.

Regards,

Jan Gerrit

P.S. this is my personal observation, not a statement Red Hat will be able to confirm or need to deny.

Is it possible to use it from some testing-repos? We would like to test on some of our internal applications...

Hi Kjetil, no - such a testing repository for being used by customers doesn't exist ... sorry. :)

Regards,
Christian

Hi Sarfaraz,

If you don't want to wait, you can install OpenJDK 11 manually - although I don't recommend to do it ! :)
Here is the download link -> https://download.java.net/java/ga/jdk11/openjdk-11_linux-x64_bin.tar.gz

Hi Sarfaraz,

Some good news for you - I just read that OpenJDK 11 will (most certainly) be available in the upcoming RHEL 7.6 edition. :)

Has anyone seen any evidence of whether OpenJDK 11 will be supported in RHEL 6? I've seen 2-3 blog posts about its availability for RHEL7, but nothing explicitly saying it won't be supported in RHEL6, just the slight implication due to its lack of inclusion in the posts.

OpenJDK11 rpms are released and available https://access.redhat.com/downloads/content/java-11-openjdk/11.0.ea.28-7.el7/x86_64/fd431d51/package

Thanks for the information, Travis ! :)

Hi Sarfaraz,

Interesting new blog article -> Migrating from Oracle JDK to OpenJDK on Red Hat Enterprise Linux: What you need to know ... :)

Regards,
Christian

Thank you Travis/Christian. We could downlaod and install openjdk 11 from repo.

However, we see that alternatives is not set as default java 11 for jdk 11 rpms when jdk 1.8 is installed. Can you please let us know why jdk 11 rpms are not setting default java to 11 when java 1.8 is already installed ?

Hi Sarfaraz,

OpenJDK 8 is the default JDK in RHEL 7 ... but you can switch default easily by executing
sudo alternatives --config java. Select OpenJDK 11 - press Enter and that's it. :)

Regards,
Christian

Christian, We do run the alternatives after installing jdk-11 to make it default.

If I install jdk rpm from Oracle, it sets the default java to 11 if 1.8 is already installed.

Will openJDK 8 continue to be default jdk for RHEL 7.x releases?

Yes Sarfaraz, I assume OpenJDK 8 will remain to be default in RHEL 7 ... OpenJDK 11 is still quite new. But I guess that will change with the RHEL 8 release, where I think OpenJDK 11 will be the default JDK. Also, you can remove ORACLE Java now, because in the article I have provided above, it reads : "Are there known issues or incompatibilities, or does OpenJDK lack something that Oracle JDK has?" ... "Oracle JDK 11 and OpenJDK 11 will be interchangeable." And, why does the ORACLE installer set JDK 11 automatically to be the default ? Well, the installer simply is coded to do this. :)

Regards,
Christian

All things clear now, Sarfaraz ? I hope I could explain everything good enough ... enjoy OpenJDK 11 on your RHEL 7.x system(s) ! :)

Regards,
Christian

Christian almost .... :) I see that OpenJDK 11 is still not available on CentOS repo. Can you please show light as to when can we expect OpenJDK 11 on CentOS repo ? Or if its already available on CentOS repo, please share the repo path.

"Almost", Sarfaraz - so cute ... hahaha :D :D :D ... seriously now : No, OpenJDK 11 isn't currently available on CentOS.
The team is working hard to get CentOS 7.6 released soon and I assume that the OpenJDK 11 packages will be made available around that release date too. :)

Regards,
Christian

Thanks a lot, Christian. That is really helpful. Appreciate the quick updates on this forum !

You're very welcome, Sarfaraz ! :) I am glad that you appreciate our assistance.

Christian

All,

java-11-openjdk and related rpms can now be found on the rpm download site of access.redhat.com

e.g.

https://access.redhat.com/downloads/content/java-11-openjdk/11.0.ea.28-7.el7/x86_64/fd431d51/package

Happy downloading

Regards,

Jan Gerrit

Yes, we know ... Travis Rogers already provided this information on October, 30th (scroll back this thread) ...
Good morning, Jan Gerrit - hope you slept well ! :D :D :D Jokes aside ... thanks for the information, my friend.

Cheers :)
Christian

All,

Where can I download RedHat's OpenJDK 11 zip installer?

Hi Reneesh,

You don't need to download a "zip installer", you execute sudo yum install java-11-openjdk ... that's all. :)

Regards,
Christian

Hi Christian,

Using a tar.gz installer I'll have more control on the installtion directory. Meaning I can untar the OpendJDK11 to my desired directory. But using yum I think it installs to default installtion directory /usr/lib...(I think). Is it possible to have yum install the OpenJDK packge to a desired directory? I've tried researching into it but cant find a solution.

Hi Reneesh,

You cannot install a RPM package to a "desired directory" ... what you can do is extract the RPM package and
move (some of) the content to a "desired directory". If everything works as expected afterwards ? Well, I don't
know. Is this the recommended way to install ? No, it's not, but you can test this on your own risk of course. :)

Regards,
Christian

Ok. Thanks Christian.

You're welcome, Reneesh ! :)
