dropwizard: Failed to parse configuration at: server.applicationConnectors; Could not resolve type id 'http' into a subtype of [simple type, class io.dropwizard.jetty.ConnectorFactory]

Using the example config in 0.7-rc1 I receive the following

example.yml has an error:
  * Failed to parse configuration at: server.applicationConnectors; Could not resolve type id 'http' into a subtype of [simple type, class io.dropwizard.jetty.ConnectorFactory]
 at [Source: N/A; line: -1, column: -1] (through reference chain: com.massrel.twitterproxy.ProxyConfig["server"]->io.dropwizard.server.DefaultServerFactory["applicationConnectors"])

Using this config:

server:
#  softNofileLimit: 1000
#  hardNofileLimit: 1000
  applicationConnectors:
    - type: http
      port: 8080
    - type: https
      port: 8443
      keyStorePath: example.keystore
      keyStorePassword: example
      validateCerts: false

I’m guessing it’s a config or documentation issue, but I’m having no luck finding the root cause as I see the HTTP type declared here https://github.com/dropwizard/dropwizard/blob/master/dropwizard-jetty/src/main/java/io/dropwizard/jetty/HttpConnectorFactory.java#L164 but I’ll admit to not being very fluent at Java. 😃
