I don't know without digging into the history. My only reason for 
pointing it out is that it looked curious as I would have expected len*4 
+ 1.  The lack of parentheses will also force every reader to stop and 
remind themselves of the precedence rules. I don't want to hold up 
JDK-8244703, I was spotted it when checking for other usages of 
utf8FromPlatform.
