Tom White commented on WHIRR-232:
---------------------------------
Thanks for taking a look, Adrian. Yes, this is what happened. There were some
instances that were started outside Whirr (they were in the stopped state, but
this wasn't the problem). With this patch the integration test passed, so I'll
go ahead and commit.
