@PreviewFeature
.
A preview feature is a new feature of the Java language, Java Virtual Machine, or Java SE API that is fully specified, fully implemented, and is yet impermanent. The notion of a preview feature is defined in JEP 12.
If a piece of code depends on a preview feature, it might stop compiling in future JDK versions in case the feature gets no positive feedback and gets removed or changed.
The inspection is enabled only if the language level of the current project is Preview.
