copying a file on a jfs filesystem, does not follow acl guidelines

Hi everyone, I have a jfs filesystem

/dev/md2 on /mnt/hd2 type jfs (rw)

to which i am trying to copy some folders into target folder /mnt/hd2/videos/movies/.

note: I am actually not using this target folder directly, but a symbolic link in my home folder that points to the target folder.

Now, the folder /mnt/hd2/videos/movies/ has default group acl enabled:

nass@stargaze:/mnt/hd2/videos$ getfacl Movies/
# file: Movies/
# owner: nass
# group: shares
# flags: -s-
user::rwx
group::rwx
other::r-x
default:user::rwx
default:group::rwx
default:group:shares:rwx
default:mask::rwx
default:other::r-x

I copied the folders from a temporary folder and expected to get the group write permission to be set as well, instead the folder looks like this:

drwxr-sr-x+ 2 nass shares        24 Aug  6 01:12 The_Movie/

I had set acls on the "videos" folder initially, and all the subfolders have inherited the default from that top folder. What have I missed?
