Currently in jdk/internal/vm/VMSupport.java , we create a JarFile without a related finally clause or try with resources. That should better be changed.
See also the Sonar check result :

    public static boolean isClassPathAttributePresent(String path) {
        try {
            Manifest man = (new JarFile(path)).getManifest();
Use try-with-resources or close this "JarFile" in a "finally" clause.Why is this an issue?
