[udig-devel] closing mapeditor results in NullPointerException (upgrade RC8->RC12)

I'm afraid I'm not sure about the first exception.  The second and  
third are probably because the renderers are still rendering after the  
map has been closed and when they finish they can't send the message  
to the rendermanager.  I can fix that issue easily enough.  Question:   
which of these are making it to the user's attention?
