Ok, I mimicked similar code in the Domain class... Just changed it to
use an enum.

Arf, with all those Java things, I forgot about the hidden C pointers
behind. I guess a
Library.free(domainsRef.getValue());
inside a finally block would do the trick.
In your other mail you mention freeing the domains pointers, but the
only method that could throw an exception is virConnectListAllDomains...
unless we need to catch also any other exception like those thrown by a
new.
