The class shapefileLoader at the location of WorldWind.src.gov.nasa.worldwindx.exampl es.util the method addRenderablesForPolygons is displaying the incorrect amount of layers due to the lack of an => sign. Here is my fixed version of the method which is just the addition of an equal sign.

Code:
protected void addRenderablesForPolygons(Shapefile shp, List<Layer> layers)
    {
        RenderableLayer layer = new RenderableLayer();
        layers.add(layer);

        int recordNumber = 0;
        while (shp.hasNext())
        {
            try
            {
                ShapefileRecord record = shp.nextRecord();
                recordNumber = record.getRecordNumber();

                if (!Shapefile.isPolygonType(record.getShapeType()))
                    continue;

                ShapeAttributes attrs = this.createPolygonAttributes(record);
                this.createPolygon(record, attrs, layer);

                if (layer.getNumRenderables() => this.numPolygonsPerLayer)
                {
                    layer = new RenderableLayer();
                    layer.setEnabled(false);
                    layers.add(layer);
                }
            }
            catch (Exception e)
            {
                Logging.logger().warning(Logging.getMessage("SHP.ExceptionAttemptingToConvertShapefileRecord",
                    recordNumber, e));
                // continue with the remaining records
            }
        }
    }
