Embedded tomcat running as windows service takes long time to stop the service

I've an executable jar file that uses embedded tomcat(9.0.44). And its running as windows service (named "MyApp Test Service") with the apache prunsrv utility. But when I try to stop the service it takes some time (more than one minute) to stop the service. But starting the service is pretty quick. I can confirm that the stop() method of the tomcat completes quickly. I suspect there is something else within the prunsrv which waits and takes time to stop the service. Please help to understand what is going on and how to resolve this(stop service right away after executing tomcat.stop())

• Registering the service - C:\ServiceTest\prunsrv.exe" "//RS//MyApp Test Service"
• Startup class and method : com.samples.myapp.TestEmbeddedServer::main
• Shutdown class and method : com.samples.myapp.TestEmbeddedServer::stop

        System.setProperty("org.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH", "true");

        this.port = port;

        this.tomcat = new Tomcat();
        this.tomcat.setBaseDir(tomcatPath);

        // Set up the context
        this.context = this.tomcat.addWebapp(contextName, webAppPath);
        this.context.setParentClassLoader(Thread.currentThread().getContextClassLoader());
    }

    public void start() throws LifecycleException {

        Connector connector = this.tomcat.getConnector();
        connector.setEncodedSolidusHandling(EncodedSolidusHandling.DECODE.getValue());
        connector.setPort(this.port);

        LOGGER.info("Starting tomcat server ...{}", this.tomcat);
        this.tomcat.start();
        this.tomcat.getServer().await();
    }

    public void stop() throws LifecycleException {
        this.tomcat.stop();
    }
}

TestEmbeddedServer.java

    private static Logger log = LoggerFactory.getLogger(TestEmbeddedServer.class);

    public static void main(String[] args) {

        String webAppDir = "D:/testserver/mysampleapp";
        String context = "/sampleapp";
        int port = 8090;

        try
        {
            tomcat = new TomcatEmbeddedServer(port, context, tomcatDir, webAppDir);
            tomcat.start();
        } catch (Exception e) {
            log.error("Failed to start tomcat server." , e);
        }
    }

    public static void stop(String[] args) {
        try {
            tomcat.stop();
        } catch (LifecycleException e) {
            log.error("Failed to stop tomcat.", e);
        }
    }
}

From these logs after the shut down signal there is exactly 1 minute delay to destroy the JVM. And I think this is where it hung.

In the prunmngr UI, the progress indicator is dismissed but the the start button is not enabled. See screenshot below.

EDIT: Results by varying the versions of Tomcat

Since Tomcat version 9.0.14 an utility executor has been introduced:

Add a scheduled executor to the Server, which can be used to process periodic utility tasks. The utility threads are non daemon by default. (remm)

Its threads are intentionally non daemon so that a server stop() does not close the JVM. To entirely stop the server you must use destroy():

    public void stop() throws LifecycleException {
        this.tomcat.stop();
        this.tomcat.destroy();
    }
