 * the provider master file would have to contain a mapping from the
 * property "GssApiMechanism.x.y.z" to an implementation class that serves
 * as the factory for that mechanism.

 * "com.foo.krb5.Krb5GssFactory", then the GSS-API framework would assume
 * that com.foo.krb5.Krb5GssFactory implements the MechanismFactory
 * interface and that it can be used to obtain elements required by for
 * supporting this mechanism.
