Project Lanai Early-Access Builds

These builds are intended for developers looking to test and provide feedback on using Project Lanai, which implements a new Java 2D graphics rendering pipeline for macOS. Since this is a macOS-specific project, only macOS builds are provided. Updated EA builds will be provided periodically, usually when there is a sufficient set of important updates since the previous EA.

Warning:

These builds are based upon the latest state of the current in development JDK, and so may contain new features and unresolved bugs unrelated to Project Lanai.

Build 16-lanai+1-51 (2020/7/3)

These early-access builds are provided under the GNU General Public License, version 2, with the Classpath Exception.

Disclaimers

• Early-access (EA) functionality might never make it into a general-availability (GA) release.

• EA functionality might be changed or removed at any time.

• The existence of EA builds does not imply that the functionality being tested will be present in any particular GA release.

• The platforms supported and the packaging options available for a GA build might be different than those available for EA builds.

• EA builds are not tested to the same level to which Oracle tests GA builds. EA builds are produced for the purpose of gathering feedback. Use for any other purpose is at your own risk.

• EA builds might be missing security-vulnerability fixes that are available in GA builds or in other OpenJDK projects.

• Oracle does not provide support for EA builds.
