I'm no expert in applet and security what do you expect us to do ?
> AccessControlException when running MINA in a Applet: RuntimePermission
> "modifyThread"

> Key: DIRMINA-659
> URL: https://issues.apache.org/jira/browse/DIRMINA-659
> Project: MINA
> Issue Type: Bug
> Affects Versions: 2.0.0-M4
> Environment: Java 5 Applet (using appletviewer)
> Reporter: Jeff Mesnil
>
> 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)
