This upgrade contains major breaking changes in foundational web server and microservice framework dependencies, requiring significant code and configuration updates.
io.undertow:undertow-core (1.4.0.Final → 2.3.21.Final): High Risk
This major version upgrade introduces support for Jakarta EE 10. Applications must be migrated from the javax.servlet.* and javax.websocket.* namespaces to the new jakarta.* namespaces. Additionally, Undertow 2.x requires Java 8 or later.
com.networknt packages (0.1.1 → 1.5.26): High Risk
This is a massive version leap from a pre-release to a mature version, introducing numerous architectural and API changes. A key breaking change is the consolidation of security configurations; framework-specific prefixes (e.g., openapi-security) must be removed and standardized under a single security.yml file.
Recommendation: A full migration and testing cycle is required. Prioritize the javax to jakarta namespace migration for Undertow compatibility, then address the configuration and API changes within the light-4j framework.
