I think I agree with Gabriel in that adding a derived property which
just used other properties is one thing, but adding a method that does a
full blown resource lookup is another, and something I would like to
avoid on model objects themselves.
As for the case described in GEOS-3049, I think just a better check on
startup will fix that, since it involves physically removing jars from
geoserver and restarting. I have not been able to reproduce a similar
issue by simply brining a database down in between two requests. The
behavior in that case seems reasonable, unless i am failing to reproduce
the real issue.
