[0.5.2-SNAPSHOT] NPE in OAuth1AuthProvider.authenticate() (LinkedIn)

[jtammen]

Hey,

today I came across this in my logs after someone tried authenticating via LinkedIn.

Caused by: java.lang.NullPointerException
    at play.api.libs.oauth.OAuth.retrieveAccessToken(OAuth.scala:52)
    at com.feth.play.module.pa.providers.oauth1.OAuth1AuthProvider.authenticate(OAuth1AuthProvider.java:118)
    at com.feth.play.module.pa.PlayAuthenticate.handleAuthentication(PlayAuthenticate.java:438)
    at com.feth.play.module.pa.controllers.Authenticate.authenticate(Authenticate.java:25)
    at controllers.Authenticate.authenticate(Authenticate.java:33)

Any hints?

Edit: I am running Play 2.2.4.

@jtammen can you write a test that shows this error?

[joscha]

@jtammen It's a caching problem - do you use multiple machines by any chance?

@joscha Sorry for the late response, I didn't see the notification for your comment.

Neither have I been able to reproduce this issue, nor did the application use multiple nodes... What kind of caching are you referring to?
