Google Cloud tool java.lang.IllegalArgumentException: Jetty ALPN / NPN incorrectly configured

Question

I am new to Google Cloud Spanner and am learning it. I started with the documentation provided by google here . To explore any database, we start with data operations and the same as me, I started by writing data to a wrench using a simple java application given here https://github.com/GoogleCloudPlatform/java-docs -samples / blob / master / spanner / cloud-client / src / main / java / com / example / spanner / SpannerSample.java .
I made changes to the driver class in the appropriate places indicated in the following code fragment:

 public static void main(String[] args) throws Exception {
            String path = "File_Path";

            SpannerOptions.Builder options = SpannerOptions.newBuilder().setCredentials(GoogleCredentials.fromStream(new FileInputStream(path)));
            options.setProjectId("Project_id");
            Spanner spanner = (options.build()).getService();
            try {
                DatabaseId db = DatabaseId.of("project_id", "spannerInstance", "Database_name");
                DatabaseClient dbClient = spanner.getDatabaseClient(db);
                run(dbClient);
            } finally {
                spanner.closeAsync().get();
            }
            System.out.println("Closed client");
        }

Now, when I try to execute the code, I get the following error:

Exception in thread "main" java.lang.IllegalArgumentException: Jetty ALPN/NPN has not been properly configured.
