Hello,
I have the same problem using an Oracle Datastore.
The problem seems to be in FeatureCollection and looks like a memory leak.
I use Geotools 8.0

Subject: [Geotools-gt2-users] SQL 2008R2 readers/iterators being left open
Hi all,
I've just started working with GeoTools, so please be gentle... but I can't
seem to determine how to resolve the "WARNING: There is code leaving feature
readers/iterators open, this is leaking statements and connections!"
problem.
As per other posts, I've added -Dgt2.jdbc.trace=true to my run configuration
(trace is below) but I'm not sure how to resolve the error/warning when I'm
not explicitly invoking an iterator.
My Maven pom is referring to -9-SNAPSHOT, SQL Server 2008 R2 x64 and I'm
using sqljdbc4.jar from the Eclipse-Juno IDE. I'm working with the following
code to add features to the map but each layer is giving me the above
warning. Here is the code:
class DisplayPlotsAction extends SafeAction
{
public DisplayPlotsAction()
{
super("DisplayPlotsAction");
putValue(Action.SHORT_DESCRIPTION, "Displays the recorded plots in
the
database.");
}
@Override
public void action(ActionEvent e) throws Throwable
{
//Create the coverage buffer zone around the selected site, if TYPE
= 1
(RAMP)
//(Site Id = 25) or RECORDING_ID = 19 or RECORDING_ID = 20
Query query = new Query("TARGET_MESSAGES_3161",
CQL.toFilter("SOURCE_ID =
25"), new String[] {"ID", "CoordGeocodePoint_SPA"});
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
System.out.println("START: " + dateFormat.format(date));
SimpleFeatureSource sfs =
ds.getFeatureSource("TARGET_MESSAGES_3161");
SimpleFeatureCollection features_25 = sfs.getFeatures(query);
Style style = SLD.createPointStyle("Circle", Color.GREEN,
Color.GREEN,
1.0f, 4f);
Layer layer_25 = new FeatureLayer(features_25, style);
map.addLayer(layer_25);
date = new Date();
System.out.println("END: " + dateFormat.format(date));
// (Site Id = 22)
Query query_22 = new Query("TARGET_MESSAGES_3161",
CQL.toFilter("SOURCE_ID = 23"), new String[] {"ID",
"CoordGeocodePoint_SPA"});
SimpleFeatureCollection features_22 = sfs.getFeatures(query_22);
Style style_22 = SLD.createPointStyle("Circle", Color.BLUE,
Color.BLUE,
1.0f, 4f);
Layer layer_22 = new FeatureLayer(features_22, style_22);
layer_22.setSelected(false);
map.addLayer(layer_22);
// (Site Id = 29)
Query query_29 = new Query("TARGET_MESSAGES_3161",
CQL.toFilter("SOURCE_ID = 30"), new String[] {"ID",
"CoordGeocodePoint_SPA"});
SimpleFeatureCollection features_29 = sfs.getFeatures(query_29);
Style style_29 = SLD.createPointStyle("Circle", Color.RED,
Color.RED,
1.0f, 4f);
Layer layer_29 = new FeatureLayer(features_29, style_29);
layer_29.setSelected(false);
map.addLayer(layer_29);
}
}// end DisplayPlotsAction class
