```text Check if these issues are valid — if so, understand the root cause of each and fix them. If appropriate, use sub-agents to investigate and fix each issue separately. P2: kotlin-spring docs now incorrectly mark `oneOf` as unsupported, contradicting generator feature declarations and likely misleading users. P3: `DebugInfo` documentation is inconsistent: the type column says `Null`, but the description still claims it maps to nullable `Object` in C#. P1: Converter incorrectly rejects null for an OAS `type: null` property, causing valid read/write payloads with `alwaysNull: null` to fail. P2: The updated model docs are internally inconsistent: the property type is `Null` but the description still says it maps to nullable `Object`, which can mislead users. P2: `useJackson3` docs were changed to exclude `apache-httpclient`, but generator code still supports it, creating a user-facing documentation/behavior mismatch. ```
