Invalid GML geometry if server locale is DE

[lgoltz]

If the locale of the server running the teamengine is DE some tests failes due to invalid GML geometries:

Here an example request from the test intersectsPolygon:

<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs/2.0" count="10" service="WFS" startIndex="0" version="2.0.0">
  <wfs:Query xmlns:ns53="http://www.deegree.org/app" typeNames="ns53:osm_protected_area">
    <fes:Filter xmlns:fes="http://www.opengis.net/fes/2.0">
      <fes:Intersects>
        <fes:ValueReference xmlns:tns="http://www.deegree.org/app">tns:geometry</fes:ValueReference>
        <gml:Polygon xmlns:gml="http://www.opengis.net/gml/3.2" gml:id="d1e1" srsName="urn:ogc:def:crs:EPSG::4326">
          <gml:exterior>
            <gml:LinearRing>
              <gml:posList>63,39 -24,04 63,39 -13,62 66,46 -13,62 66,46 -24,04 63,39 -24,04</gml:posList>
            </gml:LinearRing>
          </gml:exterior>
        </gml:Polygon>
      </fes:Intersects>
    </fes:Filter>
  </wfs:Query>
</wfs:GetFeature>

The gml:posLists contains a list of coordinates with commas instead of of points.

The following tests are concerned:

• bboxWithDefaultExtent
• invalidGeometryOperand
• nonSpecificBBOX
• intersectsPolygon

All of them creates the geometry node by Extents.envelopeAsGML():

Document gmlEnv = Extents.envelopeAsGML(featureInfo.get(featureType)
                .getGeoExtent());

This is part of geomatics-geotk [1].

As workaround the server locale can be set to EN, but it is preferred to fix this.

The org.opengis.geometry.Envelope is created by the DataSampler from geometry elements in the data sample (Extents::calculateEnvelope); these are ok. But java.text.DecimalFormat is locale-sensitive so this is probably the source of the error.

Fixed in geomatics-geotk-1.14. Format decimal values using Locale.ROOT.
