 /*
  * Author : Ram Marti
  * This is a test program to verify the fix for Bug 4326852
  * (impossible to extract a subset of private credentials)
  * The policy file used allows read access only to String classes.
  * grant {
  *    permission javax.security.auth.AuthPermission \
  *              "modifyPrivateCredentials";
  *    permission javax.security.auth.PrivateCredentialPermission \
  * "java.lang.String com.sun.security.auth.SolarisPrincipal \"user"", "read";
  * };

  * The test verifies the following:
  *      - String class creds can be retrieved by using
  *        getPrivateCredentials(String.class)
  *      - The above set is not backed internally
  *      - getPrivateCredentials(Boolean or Integer) returns an empty set
  *      - Set is returned by getPrivateCredentials() throws
  *        security exception when trying to access non-String
  *        class credentials
  *      - The above set is internally backed up and any changes in
  *        internal private creds are reflected in the set returned
  *      - When the above set throws security exception the iterator
  *      - is advanced to the next item in the list of creds.
  *      - equals,contains,containsAll,add,remove operations work correctly

	* Author : Ram Marti
	* This is a test program to verify the fix for Bug 4326852
	* (impossible to extract a subset of private credentials)
	* The policy file used allows read access only to String classes.
	* grant {

	* "modifyPrivateCredentials";
	* permission javax.security.auth.PrivateCredentialPermission \
	* "java.lang.String com.sun.security.auth.SolarisPrincipal \"user"", "read";
	* };

	* The test verifies the following:
	* - String class creds can be retrieved by using
	* getPrivateCredentials(String.class)
	* - The above set is not backed internally
	* - getPrivateCredentials(Boolean or Integer) returns an empty set
	* - Set is returned by getPrivateCredentials() throws
	* security exception when trying to access non-String
	* class credentials
	* - The above set is internally backed up and any changes in
	* internal private creds are reflected in the set returned
	* - When the above set throws security exception the iterator
	* - is advanced to the next item in the list of creds.
	* - equals,contains,containsAll,add,remove operations work correctly
