Exception while handling OAuth2 callback due to json date parsing

[pierrekilly]

When signing in with viadeo, we get the following warning and the sign in doesn't complete:

21:53:56,415 WARN : org.springframework.social.connect.web.ProviderSignInController - Exception while handling OAuth2 callback (Could not read JSON: Can not construct instance of java.util.Date from String value '2012-03-02T10:44:41.0+0100': not a valid representation (error: Can not parse date "2012-03-02T10:44:41.0+0100": not compatible with any of standard forms ("yyyy-MM-dd'T'HH:mm:ss.SSSZ", "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "EEE, dd MMM yyyy HH:mm:ss zzz", "yyyy-MM-dd"))
