Exactly the same results. No change.

Basically, I have points (lat/long) that are entered and then I attempt to create a LineString sending in these points as Coordinates. It seems that the LineString gets created fine but when adding the FeatureLayer to the map I get the following exception (seems the Envelope is null?): Dec 09, 2015 4:57:29 PM org.geotools.map.MapContent getMaxBounds WARNING: Unable to determine bounds of org.geotools.map.FeatureLayer[, VISIBLE] java.lang.NullPointerException at com.vividsolutions.jts.geom.Envelope.expandToInclude(Envelope.java:396) at com.vividsolutions.jts.geom.impl.CoordinateArraySequence.expandEnvelope(CoordinateArraySequence.java:255) at com.vividsolutions.jts.geom.LineString.computeEnvelopeInternal(LineString.java:232) at com.vividsolutions.jts.geom.Geometry.getEnvelopeInternal(Geometry.java:656) at org.geotools.data.collection.CollectionDataStore.getBoundsInternal(CollectionDataStore.java:152) at org.geotools.data.collection.CollectionDataStore.getBounds(CollectionDataStore.java:133) at org.geotools.data.AbstractFeatureSource.getBounds(AbstractFeatureSource.java:318) at org.geotools.data.AbstractFeatureSource.getBounds(AbstractFeatureSource.java:286) at org.geotools.map.FeatureLayer.getBounds(FeatureLayer.java:195) at org.geotools.map.MapContent.getMaxBounds(MapContent.java:600) at org.geotools.swing.AbstractMapPane.setFullExtent(AbstractMapPane.java:939) at org.geotools.swing.AbstractMapPane.layerAdded(AbstractMapPane.java:794) at org.geotools.map.MapContent.fireLayerAdded(MapContent.java:467) at org.geotools.map.MapContent$LayerList.add(MapContent.java:960) at org.geotools.map.MapContent$LayerList.add(MapContent.java:941) at com.jjmtechcorp.fishingtracker.FishingTrackerApp.addPointToLine(FishingTrackerApp.java:663) Here is the code snippets for creating the LineString and adding the layer: Coordinate[] positions = new Coordinate[2]; // Basically contains the 2 coordinates; Ex: coord.x = longitude; coord.y = latitude SimpleFeatureTypeBuilder typeBldr = new SimpleFeatureTypeBuilder(); typeBldr.setName("LineBldr"); typeBldr.add("line", LineString.class, mapPane.getMapContent().getCoordinateReferenceSystem()); typeBldr.add("id", Integer.class); final SimpleFeatureType lineString = typeBldr.buildFeatureType(); final SimpleFeatureBuilder BLDR = new SimpleFeatureBuilder(lineString); lineCollection = new DefaultFeatureCollection(); lineCollectionList.add(lineCollection); LineString lineString = geometryFactory.createLineString(positions); BLDR.add(lineString); BLDR.add(getLineId()); SimpleFeature lineFeature = bldr.buildFeature(null); lineCollection.add(lineFeature); Style lineStyle = SLD.createLineStyle(menuData.getColor(), 1.0f); Layer lineLayer = new FeatureLayer(lineCollection, lineStyle); map.layers().add(layerIndex, lineLayer); Any help you can provide would be much appreciated.
