Azul can help keep your Java infrastructure secure.

Learn How

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 is 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 two different support lifecycles: Long Term Support (LTS) and Medium Term Support (MTS) 

  • A release designated as LTS are those same LTS releases as designed by Oracle and the OpenJDK community. For LTS releases, Azul provides at least 8 years of access to bug fixes, security updates, and other (“Production Support”) fixes as needed 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 other Java feature releases, Azul will make feature preview or community builds available on its download page for 6 months.

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:
