The Oracle support roadmap has changed for the Oracle Java SE products¹. Starting of September 2017 and updated on September 2021, Oracle moved to a "Long Term Support" (LTS) model for Oracle Java SE products. This means that LTS versions will be targeted for release every two years (was every three years). In addition, feature (major) releases will be targeted for every six months along with quarterly maintenance/security updates. The support roadmap for the Oracle Java SE products will follow the pattern below:

Impact on Blueriq Java Runtime

Blueriq depends heavily on the JDK for much of its functionality. Since JDK 9 Oracle has a new release scheme (as described above) which also has an impact on the supported Java versions per Blueriq major as described in the paragraph Strategy. 

Strategy

Our strategy is to compile against LTS versions. This way there is no need to change your environment JDK versions every 6 months. For the non-LTS versions we aim to support them, meaning it is possible to run and create custom code/compile on the non-LTS versions. If possible we will support the next LTS version while compiling on the previous version. This way migrating to a new version of Blueriq only means changing the Blueriq version instead of the need update multiple components within your environment.

Oracle decided to deprecate several modules from the JDK in version 9 and 10 and will remove them in version 11 (e.g. the module java.xml.ws). These modules are necessary to run Blueriq (e.g. java.xml.ws is needed for webservicing purposes). Oracle will deliver these modules via third party dependencies for each matching JDK version starting from JDK 9 and up, compiled against that specific JDK version. It is not possible to add third party dependencies compiled against a higher JDK version then the one Blueriq is using. As a result, from a Blueriq perspective it is not possible to compile against JDK 8 and support JDK 11 at the same time due to the impact of changing the JDK version during the lifetime of a Blueriq major version. The Java support roadmap for the coming Blueriq releases is shown below:
