Mirror API - appcfg.sh throws a javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

[Harish Rao via StackOverflow]

I am on a Mac and using jdk 1.6.

I am trying to deploy a copy of https://github.com/googleglass/mirror-quickstart-java to google app engine using this command:

appcfg.sh --oauth2 update ./web
