Javadoc is inconsistent with oficial documentation

On the Javadocs for `DbxWebAuth` it says access tokens are valid for years:
https://github.com/dropbox/dropbox-sdk-java/blob/e8b39d1f8e6ea81b6c547ae8e66a47eb0e7be40b/dropbox-sdk-java/src/main/java/com/dropbox/core/DbxWebAuth.java#L25

However the official documentation reads:
>Dropbox access tokens are short lived, and will expire after a short period of time. The exact expiry time of a token is returned by the [token](https://www.dropbox.com/developers/documentation/http/documentation#oauth2-token) endpoint (or the redirect URI in implicit grant) - but is generally long enough for a reasonable web session.
