Summary

Test plan

  • Added test for annotated raw ArrayList return type (@Nullable ArrayList)
  • Added test for annotated raw ArrayList field type
  • All existing UseCollectionInterfaces tests pass
  • New tests verify the fix correctly transforms @Nullable ArrayList to @Nullable List

…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

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