[jira] [Created] (SSHD-332) Nio2 & security

Gaël Lalire created SSHD-332:
--------------------------------

             Summary: Nio2 & security
                 Key: SSHD-332
                 URL: https://issues.apache.org/jira/browse/SSHD-332
             Project: MINA SSHD
          Issue Type: Bug
    Affects Versions: 0.11.0
         Environment: Oracle Java 8
            Reporter: Gaël Lalire


I don't know if it is a JVM bug or normal behavior but a ProtectionDomain with no permission is associated with completionHandler thread by sun.misc.InnocuousThread class.
As a result if a security manager is set all code in completionHandler has no permission (event if policy grants all permission).

If the behavior of JVM is correct then you should add AccessController.doPrivileged() when entering completionHandler.

You can also check if a SecurityManager is set and run without Nio2 as a quick fix.
