jaotc fails to build the object file for the given class.

[Ben Evans]

Hi Tianxiao,

The jdk9-dev list strips attachments - so you will need to host the
class elsewhere.

It's probably easiest to set up a Github or other simple OSS project
and put your random class generator, and any examples of classes that
fail AOTC there, and then just give the link in your mail.

Thanks,

Ben
