Missing log of "caused by" exception when OP document metadata cannot be reached

[amergey]

Describe the bug
We cannot reach our OP server with Spring Security. We know Spring Security is not the cause of the issue, but the real cause is hidden to us because only partial stacktrace is logged:

Authorization Request failed: java.lang.IllegalStateException: org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://opserver.com/.well-known/openid-configuration": Connection reset; nested exception is javax.net.ssl.SSLException: Connection reset

Looking at the code I saw this

in

org.springframework.security.oauth2.client.web.OAuth2AuthorizationRequestRedirectFilter.unsuccessfulRedirectForAuthorization(HttpServletRequest, HttpServletResponse, Exception)

There is probably a typo

this.logger.error(LogMessage.format("Authorization Request failed: %s", ex, ex));

should be replaced with (the parenthesis is not at the right location)

this.logger.error(LogMessage.format("Authorization Request failed: %s", ex), ex);

It would allow to see the full stacktrace

Thanks for catching that @amergey. Would you like to submit a PR for this fix?
