attaching ipv6 access-list to class-map unsupported ?

[FX]

on router Cisco 7507 IOS 12.2(25)S5

I created an IPv6 access-list already on router called ABC_12.
and When I try to get these commands on router:

rot7507-3(config)#class-map CG_1_name
rot7507-3(config-cmap)#match access-group name ABC_1 <!-- Works -->
rot7507-3(config-cmap)#match access-group name ABC_12 <!- error -->
IPV6 access list is not supported in match commands

and when I try other way around i.e. define class-map followed by
Access-list, it gives
"ACL "ABC_1" is currently attached to classmap, please remove the ACL
from classmap".
