The error below has nothing to do with GeoServer, at least not directly.

The NoContentIterator is the special iterator returned when there are
no results to read,
or when an exception is throw (why that is, I have no idea, the call
is in DataFeatureCollection.openIterator() and
I don't understand why it's designed that way)
At line 56 it's preparing an exception object that will be thrown in
case you call next() regardless...
Now, the code is setup in a way that makes it hard to debug the
original exception...
Jody, do you konw why in the world do we have this code:
protected Iterator<SimpleFeature> openIterator() throws IOException
{
try {
FeatureWriter writer = writer();
if(writer != null) {
return new FeatureWriterIterator( writer() );
}
} catch (IOException badWriter) {
return new NoContentIterator( badWriter );
} catch( UnsupportedOperationException readOnly ){
}
try {
return new FeatureReaderIterator( reader() );
} catch (IOException e) {
return new NoContentIterator( e );
}
}
If the code is not able to get a writer for the collection iteration
it should simply try to get
a reader instead no? Regardless of the exception
Cheers
Andrea
