21       * Use this method to convert a GSSName and GSSCredential into a
22       * Subject. Typically this would be done by a server that wants to
23       * impersonate a client thread at the Java level by setting a client
24       * Subject in the current access control context. If the server is merely
25       * interested in using a principal based policy in its local JVM, then
26       * it only needs to provide the GSSName of the client.
27       *
28       * The elements from the GSSName are placed in the principals set of this
29       * Subject and those from the GSSCredential are placed in the private
30       * credentials set of the Subject. Any Kerberos specific elements that
31       * are added to the subject will be instances of the standard Kerberos
32       * implementation classes defined in javax.security.auth.kerberos.
33       *
34       * @return a Subject with the entries that contain elements from the
35       * given GSSName and GSSCredential.
36       *
37       * @param principals a GSSName containing one or more mechanism specific 
38       * representations of the same entity. These mechanism specific 
39       * representations will be populated in the returned Subject's principal 
40       * set.
41       *
42       * @param credentials a GSSCredential containing one or more mechanism 
43       * specific credentials for the same entity. These mechanism specific 
44       * credentials will be populated in the returned Subject's private
45       * credential set. Passing in a value of null will imply that the private 
46       * credential set should be left empty.
