        ADDITIONAL SYSTEM INFORMATION :
        jdk-21.0.2+13 later

        A DESCRIPTION OF THE PROBLEM :
        The changes made in JDK-8301247 have caused the shutdown hook to stop working.



        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Create App.java as follows.

        ```
        public class App {

            public static void main(String[] args) {

                System.out.println("java.vm.version: " + System.getProperty("java.vm.version"));

                Runtime.getRuntime().addShutdownHook(new Thread("My Shutdown Hook") {
                    public void run() {
                        System.out.println("ShutdownHook started");
                        try { Thread.sleep(3000); } catch (Exception e) { }
                        System.out.println("ShutdownHook finished");
                    }
                });

                while (true) {
                    try {
                        Thread.sleep(3000);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                    System.out.print(".");
                }
            }
        }
        ```

        ```
        javac .\App.java
        jar -cvfe libs\app.jar App *.class
        jpackage --type app-image --win-console --name app --input libs --main-jar app.jar
        .\app\app.exe
        ```

        Run the application and press Ctrl-C.


        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        We expect the shutdown hook to complete processing.
        In jdk-21.0.1+12, the shutdown hook runs and “ShutdownHook finished” is displayed.
        ACTUAL -
        In jdk-21.0.2+13, jdk-21.0.8+9, and other versions, “ShutdownHook finished” is not displayed and the shutdown hook processing is not completed.
