In case it might help someone, here's a pura Java translation of Crembo's accepted answer.

Controller method:

@GetMapping("/restart")
void restart() {
    Thread restartThread = new Thread(() -> {
        try {
            Thread.sleep(1000);
            Main.restart();
        } catch (InterruptedException ignored) {
        }
    });
    restartThread.setDaemon(false);
    restartThread.start();
}

Main class (significant bits only):

private static String[] args;
private static ConfigurableApplicationContext context;

public static void main(String[] args) {
    Main.args = args;
    Main.context = SpringApplication.run(Main.class, args);
}

public static void restart() {
    // close previous context
    context.close();

    // and build new one
    Main.context = SpringApplication.run(Main.class, args);

}
