> This PR updates the `DeferredLintHandler` so that deferred warnings can be registered during parsing, before any `JCTree` nodes have been created, and it uses this new capability to update the `"preview"` and `"text-blocks"` Lint warnings so that they can be suppressed via `@SuppressWarnings` annotations. More details are provided in additional comments.

> * #23281
> * #23400
