The proposal is to eventually get to the point that the default charset 
cannot be changed. It will take several releases to get there due to the 
potential compatibility impact. This draft JEP is the first step to 
switch to UTF-8 by default. A first step has to allow it be changed in 
order to keep some existing code/deployments working. Sorry this isn't 
clear in the JEP yet, there several clarifications to this JEP that 
haven't been included yet (on my list, I didn't realize it would be 
discussed here this week).
