Build all JDKs in Fedora against in-tree libraries and with static stdc++lib

Important.png
This is a proposed Change for Fedora Linux.
This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee.

Summary

This is initial step to move JDKs to be more like other JDKs, to build proper transferable images, and to lower certification burden of each binary. Long storyshort, first step in: https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs

This first step will move, one by one, individual JDKs in F37 to be built --with-stdc++lib=static and against in-tree (bundeld) libraries: --with-zlib="bundled" --with-freetype="bundled" --with-libjpeg="bundled" --with-giflib="bundled" --withlibpng="bundled" --with-lcms="bundled" --with-harfbuzz="bundled"

We already made a heavy testing of the behavior, and user should not face negative experience. I'm not sure if this is

Owner

Current status

  • System or Self contained change? By the changes done, this is Self Contianed Change. However from view of impact, and possible world notification, it is more System Wide Change.
  • Targeted release: Fedora Linux 37
  • Last updated: 2022-05-04
  • FESCo issue: <will be assigned by the Wrangler>
  • Tracker bug: <will be assigned by the Wrangler>
  • Release notes tracker: <will be assigned by the Wrangler>

Detailed Description

Please see https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs for whole picture

Please see https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Move_JDKs_in_RPMs_to_become_portable for this particular step. I would rather keep the details in the main page then here.

Feedback

According to short investigations, there are already precedents, where certification is a reason to build once, certificate, and repack.

According to developers, the non-portbale JDK is causing upredicted behavior different from other JDK vendors

According to JDK packagers and testers, there is to much JDKs now, and the https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Move_Fedora_JDKs_to_become_single-built.2C_portable.2C_ordinary_JDKs.2C_while_keeping_comfortable.2C_usual_system_integration is the only way out

Benefit to Fedora

Please see https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Motivation for whole picture.

This particualr proposal's main benefit will be that Fedora's JDKs as packed in RPMs will again start to resemble upstream JDKs and other vendors build, and some platfrom specific issues disappear, while JDKs remain same in view of system integration and user expereince

Scope

  • Policies and guidelines: N/A (not needed for this Change)
  • Trademark approval: N/A (not needed for this Change)
  • Alignment with Objectives:

Upgrade/compatibility impact

The compatibility and upgrade path should remain completely smooth.


How To Test

Install system JDK (java-17-openjdk) and ru your favorite application or development. No regression should be noted.


User Experience

Because of in-tree libraries, minimal image or font rendering differences canbe spotted after very detailed investigations - https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Side_effects - still, no of th e https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Known_issues should be hit by this proposal.


Dependencies

No dependent packages should notice the change.
