|We are happy to share a GeoServer 2.15-M0 milestone release with downloads (zip
|exe), documentation (html
|pdf) and extensions.
This milestone release is provided for everyone considering a Java 11 operational environment in 2019. A milestone release provides a technology preview and a chance to support the development team with early feedback: your assistance and participation is requested!
This release is a result of participation in the OSGeo Java 2018 Code Sprint and is made in conjunction with GeoTools 21-M0 and GeoWebCache 1.15-M0. We would like to thank organizations participating in the code sprint (Boundless, GeoSolutions, GeoCat, Astun Technology, CCRi) along with sprint sponsors (Gaia3D, atol, osgeo:uk, Astun Technology). Our gratitude goes out to the individuals who worked so hard to bring everything together.
Java 11 Support
The provided binary download works with either Java 8 or Java 11. Tomcat 9 or newer is required for the WAR install.
We will the update the user guide compatibility list based on your feedback and testing of this 2.15-M0 milestone release. Please note that Java 11 no longer supports the Java 2 extension mechanism used for native JAI and native ImageIO.
This is a good opportunity to review your operational environment and help test GeoServer with the environment you intend to use in 2019.
Java Roadmap Considerations
Our initial concerns with respect to continued availability of the Java 8 platform have been alleviated by industry action and commitment. Extensive Java 8 support options are now available, with RedHat making a public commitment to contribute fixes to the OpenJDK 8 codebase, and a range of organizations committed to making OpenJDK 8 builds available on a range of platforms.
Oracle has changed to a six month release schedule, donating additional components to OpenJDK to make it lead platform. Long term support (beyond six months) is being offered from a range of organizations notably RedHat OpenJDK and Adopt OpenJDK.
The net effect of these changes:
If you have been using Oracle JDK up until now it is time to review your options
Java 8 will continue to be available
The Java ecosystem is now led by the open-source Open JDK project
See the GeoTools user guide for a table outlining the Java 8 and Java 11 alternatives to consider in the year ahead.
