Facebook CertificateException

[neojonas]

I'm working on adding Spring Social into my app so users can log on using Facebook or Twitter. I followed the tutorials and samples. When I try to sign on with a Facebook account, it brings up the Facebook confirmation window to verify I want to allow my app to connect to Facebook and I hit join. Then I get a 404 and see this in the log file:

Mar 10, 2012 10:52:32 PM org.springframework.social.connect.web.ProviderSig nInController oauth2Callback
WARNING: Exception while handling OAuth2 callback (I/O error: java.security.cert.CertificateException: No subject alternative DNS name matching graph.facebook.com found.; nested exception is javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative DNS name matching graph.facebook.com found.). Redirecting to /signin

Any ideas? Thanks for the help.
