Tom White updated WHIRR-170:
----------------------------

    Attachment: WHIRR-170.patch

This patch uses LinkedHashSet instead of HashSet. It doesn't introduce role order - perhaps we can do that in another JIRA when we have a service that relies on it?

> For example, with a template "1 nn+jt, 1 dn+tt" we sometimes see the dn+tt instance launched before the nn+jt instance. This doesn't cause a problem in this case, but it's slightly confusing and easy to fix by using LinkedHashSet rather than HashSet.
