Note, not only JFS is affected. From the readdir() manpage:

Currently, only some file systems (among them: Btrfs, ext2, ext3, and ext4) have full support returning the file type in d_type. All applications must properly handle a return of DT_UNKNOWN.

So, XFS, Reiser, Fuse, and whatever comes in the future might all be affected (sorry, can't check).
