[jira] Commented: (DIRMINA-659) AccessControlException when running MINA in a Applet: RuntimePermission "modifyThread"

["Jeff Mesnil (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DIRMINA-659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12725592#action_12725592 ] 

Jeff Mesnil commented on DIRMINA-659:
-------------------------------------

+1 for documenting it.
As long as the developer can know in advance what permissions are required by MINA to work in a sandbox, it's fine.

iirc, when I tested MINA in an applet, it was the only permission required. It's a pity I have to sign the applet to allow MINA to shutdown properly (but it was a prototype applet and it is likely that a real applet would have to be signed anyway).

To sum up, +1 to document the permission(s) and close this issue

> 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)

> The exception occurs when I close the SocketConnector:
>    public synchronized void close()
>    {
>       if (connector != null)
>       {
>          connector.dispose();
>          connector = null;
>       }
>    }
