Description:
Adds distribution: oracle-openjdk for the GPLv2+CE OpenJDK builds created and hosted by Oracle at jdk.java.net.

  • Discovers current GA, early-access, and archived releases from jdk.java.net.
  • Supports SemVer ranges, exact builds, four-field versions, and legacy archive layouts.
  • Supports Linux, macOS, and Windows on x64 and AArch64.
  • Supports JDK packages; JRE and JavaFX package variants are not published by this distribution.
  • Documents that Oracle archives these builds after a limited number of releases and stops providing security updates. Users must then move to Oracle JDK or another maintained vendor to continue receiving security patches.
  • Registers the distribution, adds platform-independent tests, and updates the bundled action.

Stable release:

- uses: actions/setup-java@v6
  with:
    distribution: 'oracle-openjdk'
    java-version: '26'

Early-access release:

- uses: actions/setup-java@v6
  with:
    distribution: 'oracle-openjdk'
    java-version: '27-ea'

Using 27 without the -ea suffix selects a stable (GA) release.

Pull request overview

This PR adds support for installing Oracle-hosted OpenJDK builds from https://jdk.java.net/ via a new distribution: oracle-openjdk, including GA, early-access, and archived release discovery, plus documentation and test coverage.

Changes:

  • Adds a new OpenJdkDistribution installer that scrapes jdk.java.net to resolve and download matching JDK archives (GA/EA/archive), supporting SemVer ranges and legacy archive layouts.
  • Registers oracle-openjdk in the distribution factory and updates user docs (README + advanced usage) to document behavior and security-update caveats.
  • Adds Jest tests covering GA/EA resolution, archived releases, legacy archive headings, and platform/arch handling; updates the bundled dist/setup/index.js.
