Hi all,
In last update (1.7.0 alpha to 1.7.0 final release) we've been trying to bypass
the following error. When we access to our application with Geoserver recently
started we see two grey boxes and get two of the following exceptions:
<Doom's Day Exception>

</Doom's Day Exception>
later, when we access to it again, it works nicely (no Doom's Day Exception, so
world is still alive one more day). I don't know why could ibe possible. Don't
know if there is a cache accessed by two threads at the same time or something
like this, but i'm getting crazy.
One more thing. If i put a breakpoint in
GeoServerFeatureSource.getFeatures(Query) :
FeatureCollection<SimpleFeatureType, SimpleFeature>, only one grey tile
appears. What could be happening?
Thanks for your patience with my really poor english and have a nice day
Alberto
