All OpenJDK contributions must be provided via OpenJDK infrastructure, 
so either direct code in an email to a mailing list (attachments usually 
get stripped), or a webrev hosted on cr.openjdk.java.net (available 
directly to Authors else find someone to host for you). Links to github 
are not acceptable at this time.

That argument needs to be made via a Compatibility and Specification 
Review (CSR) request:
