That's right - the launcher explicitly overrides the classpath in that case here https://github.com/openjdk/jdk/blob/master/src/java.base/share/native/libjli/java.c#L313:


/* Override class path if -jar flag was specified */
if (mode == LM_JAR) {
    SetClassPath(what);     /* Override class path */
}
