I meant that deprecated message should be transparently explaining the 
impact of the replacement.
The proposed specs change recommends to use a replacement which is not 
equivalent to the deprecated API. And that is the reason why you don't 
like to eliminate all old API usages in the JDK code as a part of the 
fix, if I correctly understand you previous reply in this thread.
Since you are insisting that migrating to the new API is risky it is 
worth let the user know about that risk as well.
