> I'm using MINA 2.0.0-M4 within a restricted environment (an Applet in my case, could
also be JNLP).
> When running the code in appletviewer, I need to add a permission for the code to be
executed successfully:
>      permission java.lang.RuntimePermission "modifyThread";
> If I don't add this permission, the code fails with the following stack trace:
> Exception in thread "pool-2-thread-1" java.security.AccessControlException: access denied
(java.lang.RuntimePermission modifyThread)
> 	at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264)
> 	at java.security.AccessController.checkPermission(AccessController.java:427)
> 	at java.util.concurrent.ThreadPoolExecutor.shutdown(ThreadPoolExecutor.java:893)
> 	at org.apache.mina.core.service.SimpleIoProcessorPool.dispose(SimpleIoProcessorPool.java:230)
> 	at org.apache.mina.core.polling.AbstractPollingIoConnector$Connector.run(AbstractPollingIoConnector.java:512)
> 	at org.apache.mina.util.NamePreservingRunnable.run(NamePreservingRunnable.java:65)
> 	at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:650)
> 	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:675)
> 	at java.lang.Thread.run(Thread.java:613)
> The exception occurs when I close the SocketConnector:
>    public synchronized void close()
>    {
>       if (connector != null)
>       {
>          connector.dispose();
>          connector = null;
>       }
>    }
