---------------------------------------------------------------

It also looks like our setLevel(Level) implementation {{org.apache.logging.log4j.jul.CoreLogger.setLevel(Level)}}
does not perform the proper security check:

{quote}
Throws:
SecurityException - if a security manager exists and if the caller does not have LoggingPermission("control").
{quote}

Am I reading that right? If so. then that should be covered by a new issue.
