Hi Joe, 

I have changed the naming of the flag. 

What else should I add to the CSR? What is still missing?

Shouldn't the CSR cover what is submitted to the code base? I.e., 
the final state?  
What should I add to the text to cover this?  Do you want to know more
about the message texts that will be generated? Should I explain
in more detail which exceptions will get a message added?  Should
I describe the changes to NullPointerException.java?

Best regards,
