NullPointerException when gettings access grant in OAuth2Template

Since May 20 we are seeing NPEs trying to get an authentication token from Facebook:

java.lang.NullPointerException
    at org.springframework.social.oauth2.OAuth2Template.extractAccessGrant(OAuth2Template.java:304)
    at org.springframework.social.oauth2.OAuth2Template.postForAccessGrant(OAuth2Template.java:242)
    at org.springframework.social.oauth2.OAuth2Template.exchangeForAccess(OAuth2Template.java:144)
    at org.springframework.social.security.provider.OAuth2AuthenticationService.getAuthToken(OAuth2AuthenticationService.java:98)

While I suspect that this is a problem of Facebook's OAuth2 implementation I believe that this could be handled better by spring-social
