Uh, I think this is a good catch. I am not completely sure what the policy is, but here we are enhancing a non-preview method with some preview-based behavior. I would feel better if the method would refuse to work in the preview way when preview is not enabled. I.e. my opinion is that this should either be initialized to `jdk.internal.misc.PreviewFeatures.isEnabled()`, or `jdk.internal.misc.PreviewFeatures.ensureEnabled()` should be used appropriately. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/15638#discussion_r1464693259
