Message ids with no messags

["David W. Van Couvering" <Da...@Sun.COM>]

I wrote a quick test, which I'll check in, which looks for duplicate 
message ids in SQLState.jaa and message ids in SQLState.java that do not 
have a matching message in messages_en.properties.

Attached is the output.  I wonder how many of these ids are actually 
used, which is a guarantee that the user will get "UNKNOWN" when they 
get an exception.  I'm going to pare out these message ids and see what 
kind of compile errors I get...

I think this will be a good test to add to derbyall...
