Project Leyden Early-Access Builds
This is an early access build from Project Leyden. See the release notes for details.
The goal of this release is to establish a milestone and solicit feedback as we work toward integrating this functionality into the JDK. Binaries are provided as a convenience so that users do not need to build from the source code.
Warning: This build is based on an incomplete version of JDK 26.

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.
