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.
