[java] Minor updates for Java

[captn3m0]

The only weird change here is the Java SE 7's EOL date of 2019. There's differing levels of support for this from different vendors.

RedHat offered support till June 2020

AdoptOpenJDK doesn't list JDK 7.

jdk.java.net explicitly calls it out as an unsupported release:

These binaries are provided primarily for use by implementors of the Java SE 7 Platform Specification and are recommended for reference purposes only. The Reference Implementations have been approved by the JCP and will receive no further updates, not even for security issues. Binaries for development and production use will be available from Oracle and in most popular Linux distributions.

Oracle's own Java at a glance page which we link to, only mentions 8,11, and 16.

However, Oracle's release notes for Java 7 mention JDK 7u311 as the latest release (July 20, 2021)

Oracle's support roadmap page lists 2 dates:

• July 2019 for premier support
• July 2022 for extended support

with this disclaimer:

The Extended Support uplift fee will be waived for the period June 2019 - July 2022 for Java SE 7. The Extended Support uplift fee will be waived for the period March 2022 - December 2030 for Java SE 8. During this period, you will receive Extended Support as described in the Oracle Technical Support Level sections of the Technical Support Policies.

Even with this, I couldn't find a way to install JDK 7u311 without contacting Oracle Sales. Unsure of what to do here. A note in the text perhaps?

Aside: https://javadl-esd-secure.oracle.com/update/baseline.version is also a good resource

@mi-hol Any suggestions on how to handle Java 7 EoL?

(This PR updates Java, which you mentioned in #352)

[usta]

i suggest we double even tripple each java version and name them according to distributors like: 16 (oracle) 16 (adoptopen) 16 (redhat) this will let us to show different eol values in same page for each version

…

+1 to the vendoring approach, will take that up separately.

[usta]

but it is SO IMPORTANT that the product must be same , so just one Java as product name but distributors/vendors shown as versions

…

Wikipedia has some documentation on differences between vendors.

[BiNZGi]

All changes are ok 👍

[BiNZGi]

The "vendoring approach" is good also from my view. We can try and watch how complex the page will look with all the different entries.

[witchcraze]

Please let me share some topics and proposal, which may help someone's understanding or decision.
At first, I agree "vendoring approach", and I do not like Oracle.

Oracle JDK and Open JDK, Oracle and Red Hat

Oracle announced changing JAVA lisence and two types of JDK around 2017-09.
Paid support "Oracle JDK" and free "Open JDK".

Their new release model is "Feature release by 6 months", "Support free JDK by 6 months" and "Only Oracle JDK have long term support".
Free JDK user need to upgrade every 6 months to avoid EOL.
They announced this release model and they said JAVA is free. I felt Oracle was very genius.

• Oracle Java SE Releases FAQ | Oracle Java Platform Group, Product Management Blog
• JDKの新しいリリース・モデル、および提供ライセンスについて | Oracle 日本
  (Sorry, I can't search English version)

I my understanding, Oracle Java SE Support Roadmap is about "Oracle JDK", and Oracle does not provide support period table about their "OpenJDK".
By above Japanese article, their "OpenJDK" is provided at jdk.java.net and recieve quarterly update two times (means 6 months support).

After that, I understood many vendors and community would provide long term support OpenJDK.

• Leadership of OpenJDK 8 and OpenJDK 11 Transitions to Red Hat
• Java Is Still Free

Then, I think "vendoring approach" need at least "OracleJDK", "OpenJDK build by Oracle" and "OpenJDK build by Red Hat" to understand why there are many OpenJDK distributions with each own EOL.

JDK version

8u301 and 8u302 are commented in this thread.
In my understanding, latest version of "OracleJDK" and "OpenJDK buld by non Oracle" is different.
回复: [Internet]OpenJDK 8u302 Released

Distribution Issue

I think there are some similar situations.
Several providers with different EOL period.

• RHEL 8 downstreams : CentOS Linux, Rocky Linux, Alma Linux
• Elastic Search, OpenSearch by AWS (I do not know OpenSearch have EOL policy)
• Many language, middle ware, database and so on ...
  • OS vendor maintain by OS EOL (OS standard packages)
  • OS vendoe maintain by each own EOL (RHEL6,7, RHEL8)

I think showing EOL of "OpenJDK build by Red Hat" is case of "OS vendoe maintain each own EOL".
I can't judge, but supporting them will be good.
For example, we can check ...

• "PHP 7.4 Official" is supported by 2022-11
• "PHP 7.4 on Ubuntu 20.04" is supported by 2025-04
• "PHP 7.4 on RHEL 8" is supported by 2029-05

[mi-hol]

• Leadership of OpenJDK 8 and OpenJDK 11 Transitions to Red Hat

From my understanding this announcement made April 17, 2019 has already been superseded by June 19, 2020 - AdoptOpenJDK to join the Eclipse Foundation

Which in fact is superseded by March 06, 2021 Transition to Eclipse - An Update

Eclipse Adoptium is the new place for open source java as it appears

[witchcraze]

I think that sentence is about this topic
OpenJDK 8 and 11: Still in safe hands | Red Hat Developer

In February of this year, I was appointed as the new Lead of the OpenJDK 8 Update Releases Project. A couple of weeks later, I was appointed the new Lead of the OpenJDK 11 Updates Project. This is an important milestone in the history of OpenJDK and of Java SE because it's the first time that a non-Oracle employee has led the current long-term OpenJDK release project. JDK 8 is still a much-used Java release in industry, and JDK 11 is the current long-term maintenance release.

Position of "Andrew Haley" seems not changed.

• jdk8 now Main - Main - OpenJDK Wiki
• jdk8 2019-06 archive Main - JDK 8u - OpenJDK Wiki
• jdk11 now JDK11u - JDK11u - OpenJDK Wiki
• jdk11 2019-06 archive JDK11u - JDK Updates - OpenJDK Wiki

In my understanding, Eclipse Adoptium (AdoptOpenJDK) is one of popular OpenJDK distribution, but they are not Leadership of OpenJDK 8 and OpenJDK 11 now.

// Sorry, if I have any misunderstanding, please point out.
// I'm not good at English,

[mi-hol]

Well my point re the title "Leadership ... Transitions to Red Hat" is that it seems to imply that ORACLE (as corporation) was replaced by Red Hat, but in fact the corporation was replace by a foundation and the leader is just employed by Red Hat.
In other words Red Hat does NOT have the same level of control as ORACLE previously had.

At least this is my take on it. happy to be corrected on this :)

[witchcraze]

Sorry, I might not understand your comment correctly.

In my understanding, each project have relationship, but differenc project.
I feel two transition topics have different scope.

• "Leadership ... Transitions to Red Hat" is about OpenJDK project.
  This project is upstream of other OpenJDK distoribusions including Eclipse Temurin.
  They will release latest versions (7, 8, 11), and OpenJDK distoribusions will backport those update later.
• "AdoptOpenJDK to join the Eclipse Foundation" is about Eclipse Adoptium (AdoptOpenJDK) project.
  Eclipse Adoptium (AdoptOpenJDK) project have some project/tools, and they provides their OpenJDK distribution - Eclipse Temurin

If I have any misunderstanding, please point out. JAVA is too difficult for me ...

[mi-hol]

transition topics have different scope.

yes, we seem to approach the topic from different angles

[captn3m0]

Changed the EoL for 7 to be 2019.

I've created a discussion to figure out how to better handle the "so many java distributions problem" #364

Oh, and - thanks a lot @mi-hol and @witchcraze for your insights here on this thread. They were very helpful, and informative 💯.
