What I ended up having to do to get this to work is add the following to my
renderer hints:
hints.put("optimizedDataLoadingEnabled",new
Boolean(true) );
The line above is more required then a hint if doing manipulation on a
featurecollection.
the following is a full snipped of my renderer declaration, hints, and
assignment to my JMapPane(wrappedPane):
StreamingRenderer streamingRenderer=new StreamingRenderer();
Map<Object, Object> hints=new HashMap<Object, Object>();
//to prevent warning: "Assuming rendering buffer
hints.put("renderingBuffer",1);
//to prevent ConcurrentModificationException
hints.put("optimizedDataLoadingEnabled",new
Boolean(true) );
streamingRenderer.setRendererHints(hints);
wrappedPane.setRenderer(streamingRenderer);

Subject: Re: [Geotools-gt2-users] FeatureCollection Update Issue
Hi Oliver,
If the feature collection is being used in a MapLayer, clearing the
feature collection will cause an event to be fired that prompts
repainting. Try this...
mapPane.setRepaint( false );
myFeatureCollection.clear();
... // repopulate collection
mapPane.setRepaint( true );
Hope this helps.
Michael
