Once Jave 7 is instaled cannot access 5.164 and update characters with subraces Deed and Mountain dwarf. (no known way to force old version to use old Jave , even it it is on machine)
Version 6.00 does not have these subraces.
Please add the races. ( or describe how to use old version and old java)
I did a quick look. The races are present in both 5.16 and 6.0, never got removed.
Load the srd set - the dwarf subraces are part of the monster files.
No further follow up with OP. Closing as a non-issue.
