This updates the description for 
NonReadableChannelException/NonWriteableChannelException, I assume you 
didn't mean to include that in the patch.

A corner case to consider is whether a map mode can be the empty string, 
maybe IAE should be thrown for that case.

Are you planning a test to go along with this? It can test that the map 
method throws UOE and it can test the MapMode constructor.
