[lworld] RFR: 8375574: [lworld] tools/sincechecker/modules/java.base/JavaBaseCheckSince.java fails with CURRENT_PREVIEW_FEATURES

Tue Jan 27 04:00:17 UTC 2026

`ClassFileFormatVersion.CURRENT_PREVIEW_FEATURES` is a language model preview API designed to allow programs compiled without preview to write code so they can run in a preview enabled JVM. It is missing a `@PreviewFeature` annotation, correctly caught by `JavaBaseCheckSince`.
