Apache Tomcat server did not shutdowns gracefully

Question

I am trying to shutdown Apache Tomcat gracefully but it is not getting shutdown properly and gets hang may be because of Apache Camel or Hazelcast Jet not sure on context destroy I am shutting down the Hazelcast Jet instance still it not. Below is my context destroy code

public static void contextDestroyed() {
    try {
        if (executor != null) {
            executor.shutdown();
        }
        if (hazelcastjetInstance != null) {
            hazelcastjetInstance.getCluster().shutdown();
            //hazelcastjetInstance.shutdown();
        }
        AbandonedConnectionCleanupThread.checkedShutdown();
        Runtime.getRuntime().gc();
    } catch (Exception e) {
     e.printStackTrace()
    }
}

and error which is I am getting while shutdown in tomcat (sorry my log is little bit long)
