 This exception is thrown by the AccessController to indicate
that a requested access (to a critical system resource such as the
file system or the network) is denied.
 The reason to deny access can vary.  For example, the requested
permission might be of an incorrect type,  contain an invalid
value, or request access that is not allowed according to the
security policy.  Such information should be given whenever
possible at the time the exception is thrown.
