Probably one of the gemoetry attributes was just (for instance 0) so that it
got encoded as a property with an integer type not a "double" as expected.
Probably the SimplePointEncoder should be a bit more forgiving and use
Number.doubleValue() on the actual value it gets back.
so changing decodeGeometry to:
public Geometry decodeGeometry(PropertyContainer container) {
double x = ((Number)
container.getProperty(xProperty)).doubleValue();
double y = ((Number)
container.getProperty(yProperty)).doubleValue();
Coordinate coordinate = new Coordinate(x, y);
return getGeometryFactory().createPoint(coordinate);
}
