## Summary For Java Records, `POJOPropertiesCollector._removeUnwantedIgnorals()` records a `@JsonIgnore`-annotated component under its original implicit name before `_renameUsing()` applies the `PropertyNamingStrategy`. After the rename, `_ignoredPropertyNames` still holds only the pre-rename name, so `_ignorableProps` is built from the stale key. The renamed JSON key passes `IgnorePropertiesUtil.shouldIgnore()` and is assigned to the Record's constructor parameter, defeating the `@JsonIgnore`.

## Impact A Record using a naming strategy that relies on `@JsonIgnore` to keep an internal/privileged component out of deserialization can have that component set from the wire via its renamed key (e.g. a role/flag controlled by an untrusted client).
