Issue - The openId gmail authentication, built on top of springsecurity, stopped to work on my website and I got this error:
org.springframework.security.authentication.AuthenticationServiceException: Unable to process claimed identity 'https://www.google.com/accounts/o8/id'
Reason - in the class OpenID4JavaConsumer
error: org.openid4java.discovery.DiscoveryException: 0x70d: Error parsing XML document
Solution
I fixed the issue by updating the version of xmlParserAPIs and xercesImpl from 2.5 to 2.6.x.
The wrong version for xmlParserAPIs and xmlParserAPIs was brought by jcaptcha so I had to exclude those two.
See this link on jugevents.
