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

[jira] Commented: (DIRMINA-659) AccessControlException when running

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

Apparently it's needed by :

I'm no expert in applet and security what do you expect us to do ?

----------------------------------------
Assignee: Edouard De Oliveira
Isn't some documentation the real solution here ?
Maybe a special section for restricted envs like applets in the wiki
Jeff you can also sign your applet which will give your applet an unrestricted access to the system and thus eliminate the issue.
