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)

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