@Exported public class ConfigFile extends Configuration
javax.security.auth.login.Configuration.
  This object stores the runtime login configuration representation,
 and is the amalgamation of multiple static login
 configurations that resides in files.
 The algorithm for locating the login configuration file(s) and reading their
 information into this Configuration object is:
 
URL pointing to a
   login configuration file to be loaded.  Read in and load
   each configuration.
 java.lang.System property
   java.security.auth.login.config
   may also be set to a URL pointing to another
   login configuration file
   (which is the case when a user uses the -D switch at runtime).
   If this property is defined, and its use is allowed by the
   security property file (the Security property,
   policy.allowSystemProperty is set to true),
   also load that login configuration.
  The configuration syntax supported by this implementation
 is exactly that syntax specified in the
 javax.security.auth.login.Configuration class.
