java.security.AccessControlException : Access denied (java.lang.RuntimePermission modifyThread)

Question

I have my Batch Application Program, in which I am using ThreadPoolExecutor in my Batch Application Program. So as soon as it hits the-

executorService.shutdown();

line in my Batch Application program, I always get this below error in my Batch Application Program. And I am not able to ShutDown my own Executor Service. Can anyone suggest me how should I overcome this error.

Batch Execution Failed!
TaskResponse[exitCode=
   <ExitCode 
       type="User"
       code="30"
       msg="Unexpected error encounted"/>,
    causedByException=java.security.AccessControlException : Access denied (java.lang.RuntimePermission modifyThread)

Update- I tried doing this way, but still no luck-

// create thread pool with given size
            final ExecutorService service = Executors.newFixedThreadPool(10); 

            // queue some tasks
            for(int i = 0; i < 3 * 10; i++) {
                service.submit(new ThreadTask(i));
            }


            AccessController.doPrivileged(new PrivilegedAction() {
                public Object run() {
                    // privileged code goes here, for example:
                    service.shutdown();
                    try {
                        if (!service.awaitTermination(Long.MAX_VALUE, TimeUnit.DAYS)) {
                            service.shutdownNow();
                        }
                    } catch (final InterruptedException pCaught) {
                        service.shutdownNow();
                        Thread.currentThread().interrupt();
                    }

                    return null; // nothing to return
                }
            });

Don't run your batch test code with a SecurityManager. Or, grant your code the modifyThread RuntimePermission.

I have to run my Batch Test Code using Security Manager as I think its part of framework. How can I grant my code modifyThreadRunttimePermission? – arsenal May 21 '12 at 01:31

You can try to shutdown your Executor in a doPriviledged block

AccessController.doPrivileged(new PrivilegedAction() {
            public Object run() {
                // privileged code goes here, for example:
                executorService.shutdown();
                return null; // nothing to return
            }
        });

Well if this doesn't work, then you should try what jtahlborn suggested - grant your code appropriate rights. – Svilen May 28 '12 at 05:47
I am not sure how should I grant my code appropriate rights? Can you help me with that? – arsenal May 28 '12 at 05:49
This is quite a topic on its own. This might help http://java.sun.com/developer/onlineTraining/Programming/JDCBook/appA.html. You should also have a look at the Java tutorial. Do a search on StackOverflow also - surely similar questions have been asked. – Svilen May 28 '12 at 05:57
