Java SE’s release train and support roadmap have changed to support a much more rapid evolution of the Java SE platform. Starting with JDK 9, Java SE standards promulgated by the JCP and the associated OpenJDK implementation established new versioning nomenclature and a new release cadence for all Java releases.
Here’s what’s new:
- Oracle and the OpenJDK community are moving to a Long Term Support (LTS) release model plus a new class of “Feature” releases.
- LTS releases are scheduled every 3 years. These are comparable in scope to prior major releases of the JDK, like JDK6, JDK7 and JDK 8.
- Availability of public updates for LTS releases are planned for only 6 months after general availability (GA). LTS updates after the first 6 months are available only through paid commercial support from Oracle.
- Feature releases introduce new features before the next LTS release and appear twice per year, currently targeted to be released every March and September. Feature releases will only be maintained and supported by Oracle in the OpenJDK project for 6 months, aligning the GA of each new feature release with the end of life of the prior feature release.
The next LTS release after JDK 8 is JDK 11, scheduled for September 2018.
- JDK 9 (GA in September, 2017) and JDK 10 (GA scheduled in March, 2018) are feature releases.
- JDK 12 (GA scheduled in March, 2019), and JDK 13 (GA scheduled in September, 2019), etc. are all feature releases leading up to the next LTS release (JDK 17) scheduled in September, 2021.

This new Java SE release cadence has several challenges and shortcomings:
- Beginning with JDK 11, Oracle’s public JDK updates end concurrent with the GA of a new release. For example, Oracle will no longer offer public updates for JDK 8 once JDK 11 is released in September, 2018.
- As JDK 11 will take time to become production-worthy, this “support cliff” presents major challenges and stability risks, forcing users of public updates to choose between using an immature release or one with known security vulnerabilities.
- The frequent feature releases enable access to new capabilities in the JDK/JVM well before the next LTS, but their zero-overlap “support cliff” makes them problematic for production use, as there is no smooth transition path from one stable and updated version to the next.
How Zulu Enterprise Addresses these Challenges
Zulu Enterprise releases align with Oracle’s and OpenJDK’s general availability for all releases of Java SE, but offer overlapping support coverage from one release to the next. Zulu Enterprise customers have access to all bug fixes, enhancements, and quarterly and emergency security updates. Azul also makes out-of-cycle bug fixes and security updates for its commercial customers, with our fixes contributed back to the OpenJDK community.
Zulu Enterprise offers Long-Term Support (LTS) for the same releases designated by Oracle and the OpenJDK community as LTS, and provides 8-year access to bug fixes, security updates, and other fixes as needed (“Production Support”) plus 2 years of additional support intended to advise and assist users to migrate to a newer JDK version (“Extended Support”).
In addition to support for the once every 3-year LTS releases, which are ideal for long-term production use, Zulu Enterprise also provides Medium-Term Support (MTS) for certain Java releases. MTS releases enable practical use in production deployments of the new capabilities available in feature releases without having to wait for the next LTS release. Azul designates one MTS release per year in the years between LTS releases and provides support, bug fixes and security updates for 18 months past the GA date of the following LTS release, ensuring support overlap and a smooth transition path for production deployments, plus 12 months of Extended Support.
Finally, Zulu Enterprise provides Short-Term Support (STS) for the remaining Java SE feature releases. STS support allows users the earliest access to new Java features and with sufficient support, bug fixes and security updates to allow a smooth transition to a newer JDK release. For an STS release, Zulu Enterprise provides for 12 months of Production Support plus 6 months of Extended Support (18-month lifecycle).
