Hi Benoit,
There are properties you can set in the annotation model on epackage level which control if join tables are created for
associations (contained or non-contained). As a default for containment associations no-join table is used and for
non-containment associations a join table is used.
Does this answer your question?

from what I can see on hudson, the last build (containing those updates)
didn't run.

Ha indeed! I did not abort it, not sure what happened, I kind of was focused on if the small icon was red, and did not
see the difference between grey and blue...
Doing a new build now!
