I was thinking to move the entire doPrivileged block to mergeWithSystemLogger that will look like:

    if (cfg == system.config) {
        return;
    }

    // sanity check
    if (!system.isSystemLogger …. 
	throw new InternalError(…);
 
    final ConfigurationData cfg = config;
    AC.doPrivileged(...
       config = cfg.merge(system);
    )


 577         checkPermission();

Is this necessary?   Is it be covered by the merge method?
