RuntimeDetector now derives the correct PropertiesLauncher FQN from the JAR manifest Main-Class package. Spring Boot 3.2+ uses org.springframework.boot.loader.launch.PropertiesLauncher, pre-3.2 uses org.springframework.boot.loader.PropertiesLauncher. DockerRuntimeOrchestrator uses the detected class instead of a hardcoded 3.2+ reference, falling back to 3.2+ when not auto-detected.
