## 4.6.3

**`(fix):`** Fix Java SDK snippet and wire test generation for `allow-multiple` query
parameters when `coerce-optional-schemas-to-nullable: true` is set.
Previously, list items wrapped in `optional<...>` and/or `nullable<...>`
produced calls like `.strategy(Arrays.asList(Optional.of(...)))`, which
failed to compile because the generated builders only expose `List<T>`
overloads (no `List<Optional<T>>` or `List<Nullable<T>>`). The snippet
generator now strips both `optional` and `nullable` wrappers from list
items, so the emitted code matches an existing builder signature.
