 * SECURITY issue.
 *
 * See bug 11874
 *
 * The solution to both is to move doPrivilege UP within AXIS to a
 * class that is either private (cannot be reached by code outside
 * AXIS) or that represents a secure public interface...
 *
 * This is going to require analysis and (probably) rearchitecting.
 * So, I'm taking taking the easy way out until we are at a point
 * where we can reasonably rearchitect for security.
