…and fully-qualified types This commit fixes two related issues: 1. Issue #713: NPE with annotated raw collection types When a method or field has an annotated raw collection type (e.g., `@Nullable ArrayList`), the recipe would throw a ClassCastException because it incorrectly assumed that annotated types always wrap parameterized types. Raw types are represented as `J.Identifier`, not `J.ParameterizedType`. 2. Issue #716: ClassCastException with fully-qualified type names When using fully-qualified type names (e.g., `java.util.HashSet`), the recipe would throw a ClassCastException because these are represented as `J.FieldAccess`, not `J.Identifier` or `J.ParameterizedType`. The fix adds proper handling for all these cases: - Raw types (`J.Identifier`) - Fully-qualified types (`J.FieldAccess`) - Parameterized types (`J.ParameterizedType`) - All of the above when wrapped in annotations (`J.AnnotatedType`) Fixes #713 Fixes #716 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

I am not sure. Should we de-duplicate between visitVariableDeclarations and visitMethodDeclaration?
