So this happens when you try to add a privilege to an ACL that does not exist:

SQL> EXEC DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE ('myacl.xml', 'SIMON', true, 'connect');
BEGIN DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE ('myacl.xml', 'SIMON', true, 'connect'); END;

ERROR at line 1:
ORA-31001: Invalid resource handle or path name "/sys/acls/myacl.xml"
ORA-06512: at "SYS.DBMS_NETWORK_ACL_ADMIN", line 384
ORA-06512: at line 1

Oracle Database 11g introduced fine-grained access control to external network services using Access Control Lists (ACLs). This basically allows you to take control over which users access which network resources, regardless of package grants.
