Risk Level: High

• Breaking Changes: High (JSON processing is core functionality)
• Testing Required: Comprehensive REST API testing
• Dependencies: Affects all JSON-based APIs

No files or tests are identified. Start by locating the repackaged Jackson dependency declarations and the JSON serialization, deserialization, and REST API entry points they affect. Done means using standard Jackson Core, Databind, and Annotations versions, preserving API compatibility, passing all tests, and completing the requested endpoint and performance checks.
