The jdk9-dev list, like most OpenJDK mailing lists, retains attachments
of the following content types:

  multipart/mixed
  multipart/alternative
  text/plain
  text/x-diff
  text/x-patch
  message/rfc822
  multipart/signed

So if you want to attach a `.java` source file, just attach it as
text/plain.

For IP clarity, many OpenJDK contributors will never follow such a link.
Material contributions (bug reports, patches, documentation, etc.) must
come in via OpenJDK infrastructure.
