Starting with JDK 9, Java SE standards promulgated by the JCP and the associated OpenJDK implementation establish new versioning nomenclature and a new release cadence for all Java releases, including Long Term Support (LTS) releases plus a new class of “feature” releases.  General availability of LTS releases are scheduled every 3 years, with additional feature releases every six months.

Azul product releases align with Oracle’s and OpenJDK’s general availability for releases of Java SE.  Azul customers have access to bug fixes, enhancements, and quarterly and emergency security updates.

Azul’s commercial product releases are designated with one of three different support lifecycles: Long Term Support (LTS), Medium Term Support (MTS), or Short Term Support (STS):

  • A release designated as LTS are those same LTS releases as designed by Oracle and the OpenJDK community. For LTS releases, Azul 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”).
  • For those releases designed as MTS, Azul provides Production Support for at least 1.5 years after the general availability of the next LTS release, plus an additional 1 year of Extended Support.
  • For those releases designed as STS, Azul provides Production Support for 12 months from the general availability of that release, plus an additional 6 months of Extended Support.

The table below details the class of support lifecycle for each existing and planned JDK release for Azul’s products, in addition to the expected availability of public updates and the lifecycle of Oracle’s commercial Java support offerings:
