During runtime execution, the application logs a terminal deprecation warning stemming from the internal reflection mechanisms of the XStream dependency (com.thoughtworks.xstream:xstream:1.4.21).
The Java Virtual Machine (JVM) issues this alert because XStream directly invokes internal JDK methods (sun.misc.Unsafe). Although this warning standardizes globally in newer Java editions, our underlying Java 21 runtime build has backported JEP 471 security logs.
The application boots up and operates successfully, but this log message clutters environment traces and indicates long-term breaking change risks.
