I'm trying to fill a Rectangle shaped vertex in Jung, as mentioned in exmaples and docs, I used a Transformer:

 Transformer<String, Paint> vertexColor = new Transformer<String,Paint>() 
 public Paint transform(String i) 
 return Color.WHITE;
 
 ;

and right after the instruction:

 vv.getRenderContext().setVertexFillPaintTransformer(vertexColor);

where vv is VisualizationViewer.

But the Transformeris not working, it continues to say Type mismatch: cannot convert from Color to Paint though many tutorials show the same lines.

The complete method is:

 @PluginVariant(requiredParameterLabels = 0)
public static JComponent visualize(final UIPluginContext context, final OWLOntologia ontology) 

 JPanel base = new JPanel();

 Graph<String, String> grafo = OntologyGraph.getGraph(ontology);

 Layout<String, String> layout = new TreeLayout<String, String>((Forest<String, String>) grafo);
 layout.setSize(new Dimension(300, 300));
 VisualizationViewer<String, String> vv = new VisualizationViewer<String, String>(layout);
 vv.setPreferredSize(new Dimension(300000, 300000));

 Transformer<String, Shape> vertexShape = new Transformer<String, Shape>()
 @Override
 public Rectangle transform(String arg0) 
 Rectangle nodo = new Rectangle();
 nodo.height = 80;
 nodo.width = 200;

 return nodo;
 
 ;


 Transformer<String, Paint> vertexColor = new Transformer<String,Paint>() 
 public Paint transform(String i) 
 return Color.WHITE;
 
 ;


 vv.getRenderContext().setVertexFillPaintTransformer(vertexColor);
 vv.getRenderContext().setVertexShapeTransformer(vertexShape);
 vv.getRenderContext().setVertexLabelTransformer(new ToStringLabeller<String>());
 vv.getRenderContext().setEdgeLabelTransformer(new ToStringLabeller<String>());
 vv.getRenderer().getVertexLabelRenderer().setPosition(Position.CNTR);

 final DefaultModalGraphMouse<String, Number> graphMouse3 = new DefaultModalGraphMouse<>();
 vv.setGraphMouse(graphMouse3);
 graphMouse3.setMode(DefaultModalGraphMouse.Mode.PICKING);

 base.add(vv);

 return base;

What do your imports say? My guess is that either your Color or Paint got imported from javafx (or somewhere else other than java.awt).
