JDK 18

This release will be the Reference Implementation of version 18 of the Java SE Platform, as specified by JSR 393 in the Java Community Process.


JDK 18 is in Rampdown Phase Two. The overall feature set is frozen. No further JEPs will be targeted to this release.

The stabilization repository, jdk18, is open for select bug fixes, with approval, per the JDK Release Process (JEP 3). Late enhancements are still possible, with approval, but the bar is now extraordinarily high.
