Hi David,

Thanks for letting me know about the attachment stripping behaviour, and
reminding me about the current state of the JDK 9 release schedule.

Stuart, would you be happy to host my patch on cr.openjdk.java.net? If not,
do you know who else might be happy to host it for me? Or alternatively,
would you prefer I wait until development of Java 9 Updates and/or Java 10

Kind regards,
