Hi Aleksey,

Thanks for the review.  The plan is to first change the runtime to 
accept version 53 files and then change the tools to generate them. 
Hopefully, this will reduce incompatibility problems.  See JDK-8148651 
<https://bugs.openjdk.java.net/browse/JDK-8148651> for details.

Thanks, Harold
