[H3] Ubuntu 26.04 LTS Container Support and Default Ubuntu Version Change
Ubuntu 26.04 LTS (Resolute Ringtail) has been released with support until April 2031. We are pleased to announce that Eclipse Temurin now provides container images for Ubuntu 26.04 LTS across all supported architectures.
Important: With this release, the default Ubuntu base image for Eclipse Temurin containers has been updated from Ubuntu 24.04 (Noble) to Ubuntu 26.04 (Resolute). This means that untagged or version-only tags (e.g., eclipse-temurin:26-jdk) now point to Ubuntu 26.04-based images. If you need to continue using Ubuntu 24.04-based images, please use the explicit noble tag (e.g., eclipse-temurin:26-jdk-noble).
Container support has been added for Ubuntu 26.04 across the following architectures:
aarch64 (ARM 64-bit)
arm (ARM 32-bit)
ppc64le (PowerPC 64-bit Little Endian)
s390x (IBM Z)
x64 (x86-64)
Note for riscv64 users: Due to upstream official images limitations, we are currently unable to build riscv64 images for Ubuntu 26.04. If you require riscv64 support, please continue using the -noble tag (Ubuntu 24.04) for now.
Docker images are available for all supported JDK versions (8, 11, 17, 21, 25, 26) in both JDK and JRE variants. For the full list of available tags and their respective Dockerfiles, please refer to the official Eclipse Temurin Docker documentation.

[H1] Exploring Packaging Changes to Temurin JDK on AIX, Linux ppc64le and Linux s390x
We are proposing changes to how Eclipse Temurin runtimes are packaged on selected platforms and are seeking community feedback.
[IMG: Adoptium PMC]
Adoptium PMC·May 05, 2026·3 min readThe Adoptium community is committed to delivering high-quality Eclipse Temurin builds for the most widely used and actively maintained platforms. As part of this, we regularly review how our binaries are packaged and distributed to ensure they align with modern usage.
We are opening a discussion on a proposal to evolve runtime packaging for a small number of platforms where usage patterns are heavily backend-focused.
[H2] Platforms in Scope
This proposal specifically targets:
AIX ppc64
Linux ppc64le
Linux s390x
These platforms are predominantly used for server-side and enterprise workloads, where GUI support is rarely required.
[H2] Proposal Overview
We are exploring a shift toward more streamlined runtime distributions on these platforms, with a focus on:
Prioritising headless or minimal runtime configurations
Reducing overlap between existing runtime variants
Aligning delivered artifacts with typical production usage
This would affect how runtimes are packaged and distributed, not the underlying OpenJDK functionality.
[H2] Rationale
Across the Java ecosystem, usage has shifted toward:
Cloud and container-based deployments
Backend services with no GUI requirements
Increased emphasis on smaller, more efficient runtime images
Maintaining multiple overlapping runtime variants introduces additional build, test, and maintenance overhead. As seen in previous platform decisions, focusing effort where it delivers the most value helps improve overall quality and sustainability. As this proposal involves removing the GUI related components, such as libawt_xawt.so on the Linux platforms, it would align these builds more closely with the existing Alpine Linux distributions, which already exclude this library. In practice, this means the resulting runtimes would be comparable in functionality to Alpine-based Temurin builds. For typical backend workloads, including those using ImageIO, no impact is expected. However, this will be validated through targeted testing to ensure compatibility and avoid regressions.
[H2] What This Means
No decisions have been made at this stage. This is an early proposal intended to gather feedback.
If adopted, the changes would aim to:
Simplify the set of runtime packages on these platforms
Improve maintainability of build and test pipelines
Full-featured runtimes would continue to be considered where there is a clear need.
[H2] Feedback Requested
We are particularly interested in feedback on:
Current usage of GUI features on these platforms
Requirements for full vs headless runtimes
Potential impact to existing deployments and automation
If your organisation depends on these platforms, please share your use cases and requirements in the discussion.
[H2] Join the Discussion
We encourage all users and contributors to participate:
See: https://github.com/adoptium/adoptium/issues/273
[H2] Summary
This proposal reflects an ongoing effort to align Eclipse Temurin distributions with modern deployment patterns, while ensuring that project resources are focused where they provide the greatest benefit.
By starting with AIX ppc64, Linux ppc64le, and Linux s390x, we aim to evaluate this approach on platforms where it is most applicable.
We welcome your feedback.

[H2] New and Noteworthy
[H3] Headless JRE RPM Packages Available For JDK26
For server environments where no graphical components are required, a new headless JRE package is also available. This excludes GUI-related libraries such as AWT and reduces the overall installation footprint.
sudo dnf install temurin-26-jre-headless
[H3] Coexistenance of JDK & JRE (via RPM installation) Is Now Prevented
Following the discussion in this Temurin issue, https://github.com/adoptium/installer/issues/1360 from JDK26 onwards, the installation of both the JDK & JRE RPM packages is no longer allowed. This is because the temurin-26-jre package takes the jdk-26-jre.tar.gz and installs it. The tar ball is the result of the legacy-jre-image target, which is a different jlink invocation than the full JDK.
For the JDK it includes all modules for legacy-jre-image it includes an (arbitrary) subset. With JDK 9+ there is no JRE that is a proper subset of the JDK. The lib/modules file differs depending on which modules got linked in. Therefore, there is no way one package can own that file and be a true subset (in terms of RPM packaging). It makes little sense to have two "runtimes" installed at the same time for any major version.
One, call it R, including module set A
Another, call it R', including module set B
Where:
A ⊂ B
files(R) ∩ files(R') ≠ ∅
