That does indeed look like it might be related.  I'm not exactly sure what
the GWS query engine is or when it is involved in querying features, but if
I am interpreting this correctly, this would mean that ANY left outer join
would behave like an inner join.  The severity is marked as "trivial", which
leaves me confused - I would expect a left outer join to be rather common
and necessary.  I didn't think I was doing something all that special.  In
fact, this was the only join type available back in 1.1.  I guess I will
have to submit a defect just to be sure.

I think you are correct that the surrounding behavior of errors might be
Studio issues.  The problem only appears after I refresh the preview of the
joined layer and restarting the service makes the errors stop.  Displaying
the preview via Maestro does not cause the feature source to break, but
Maestro shows the preview in a slightly different way.

Thank you for your advice and suggestions!
