Build 11 of the JDK 28 early-access program is available for Linux (AArch64/x64), macOS (AArch64), and Windows (x64) under the GPLv2 with Classpath Exception. As with all early-access builds, features may be added, changed, or removed before general availability, and the builds may lack security fixes present in GA releases. Feedback can be submitted through Java's bug-reporting channel, and source distribution is subject to export restrictions for certain countries.

What license are the JDK 28 early-access builds released under?
They are released under the GNU General Public License, version 2, with the Classpath Exception (GPLv2+CE). This is the standard OpenJDK licensing model, and build 11 of the JDK 28 early-access program is distributed under these terms for Linux (AArch64, x64), macOS (AArch64), and Windows (x64). Track OpenJDK licensing and release details for JDK 28 alongside other dev updates on daily.dev.
Are JDK early-access builds safe to use in production?
No, early-access (EA) builds like JDK 28 build 11 are not tested to the same level as general-availability builds and Oracle provides no support for them. They may be missing security-vulnerability fixes available in GA builds, and any feature present in an EA build might be changed, removed, or never make it into the final GA release. Developers evaluating JDK 28 features before GA can follow OpenJDK progress on daily.dev.
