IBM Semeru Runtime Certified Edition for z/OS

Information in this support guide does not apply for the IBM Semeru Runtime Certified Edition for z/OS. Refer to this resource:

Overview

The IBM Semeru Runtimes are free to download and use in both personal and commercial environments. Quarterly security updates and bug fixes are also made available, free of charge. The packages are built and tested by IBM to meet the high quality standards that a business expects for running mission-critical Java applications. You can read more about our quality standards here.

The IBM Semeru Runtimes contain OpenJDK class libraries from the OpenJDK community and the Eclipse OpenJ9™ Java virtual machine from the Eclipse Foundation. IBM participates in both of these projects to drive new innovation, improve test coverage, and help fix any problems that are identified.

For any problems with OpenJDK class libraries or the OpenJ9 VM, free support is available directly from these communities.

  • For OpenJDK class library problems, open an issue in the JDK Bug System.
  • For OpenJ9 VM problems, ask questions in the OpenJ9 slack channel (click here for an invite) or raise an issue in the OpenJ9 GitHub repository.

If your business needs enterprise-grade support for some or all of your Java deployments, IBM provides a commercial support offering, IBM Runtimes for Business.

Support for the IBM Semeru Runtimes is included as part of the installation of an IBM Product, and is included in the support entitlement for the IBM operating system or other IBM product that includes it. The customer must contact IBM Support to open a ticket against the relevant IBM product.

Life Cycle

The release cadence of the IBM Semeru Runtimes are expected to track the upstream OpenJDK releases:

  • A new feature release will be delivered every six months
  • A maintenance/security update based upon each active release every three months.
  • Every two years a feature release will become a Long Term Support (LTS) release.

Available support will depend on whether the release is a feature release or an LTS release:

  • LTS releases
    IBM will continue to support LTS releases, at a minimum, as long as the corresponding upstream/OpenJDK source is actively maintained.
  • Feature releases
    No IBM support is available for feature releases.

The following table summarizes the support status of the IBM Semeru Runtimes. All future dates and support expectations are predictions that might change depending on how the OpenJDK and OpenJ9 projects evolve over time.

IBM Semeru Runtimes version Release type GA1 OpenJDK EOS2 EoA3
23 Feature Sep 2024 Mar 2025 Mar 2025
21 LTS Jan 2023 Dec 2029 Dec 2029
17 LTS Dec 2021 Oct 2027 Oct 2027
11 LTS Sept 2021 Oct 2027 Oct 2027
8 LTS Jul 2021 Nov 2026 Nov 2026

Notes:

1. The General Availability (GA) date listed is the latest date that a release of the offering is available to all users, regardless of language or media.

2. The EOS (End of Service) date is the date when IBM expects upstream/OpenJDK maintenance to end.

3. The EoA (End of Availability) date is the timeframe IBM expects our maintenance stream to end.

4. Version 22 and earlier Feature releases are no longer maintained or receiving security fixes. We recommend that you migrate to an actively maintained LTS or Feature release.

5. For life cycle information for the IBM i operating system refer to the Java on IBM i page.

6. Life cycle information for z/OS is available from the IBM Support product lifecycle page.

If you are using IBM Semeru Runtimes that are incorporated into an IBM or Vendor product, EOS dates might differ from those in the table:

Supported platforms

The IBM Semeru Runtimes function on a range of platform architectures and operating systems. This range is expected to extend as and when new architectures are adopted by the OpenJDK and Eclipse OpenJ9 communities.

Support information for these operating systems is documented elsewhere:

Note: When public support for an operating system version ends, the IBM Semeru Runtimes can no longer be supported on that level.

The IBM Semeru Runtimes are expected to function with the following operating systems and minimum levels:
