Hi Team, We have a bunch of application working with RH_SSO. The applications were using SAML adapter 7.0 for EAP6 and all was working fine. However we upgraded the SAML adapter to 7.1 at out SP side. Soon after the upgrade we are now seeing XML parsing exceptions in the /wapps/xxx/saml endpoint created by the adapter. These are also not consistent and most of the applications works fine most of the time however we get this mostly with one of our SP. Please find the stack trace below 2017-06-09 03:17:42,370 [wapps-external-exec-threads - 161] ERROR [org.keycloak.saml.common] Error in base64 decoding saml message: java.lang.RuntimeException: javax.xml.stream.XMLStreamException: java.net.MalformedURLException 2017-06-09 03:17:42,370 [wapps-external-exec-threads - 161] ERROR [org.apache.catalina.connector] JBWEB001018: An exception or error occurred in the container during the request processing: java.lang.NullPointerException at org.keycloak.adapters.saml.profile.AbstractSamlAuthenticationHandler.handleSamlResponse(AbstractSamlAuthenticationHandler.java:179) at org.keycloak.adapters.saml.profile.webbrowsersso.SamlEndpoint.handle(SamlEndpoint.java:44) at org.keycloak.adapters.saml.SamlAuthenticator.authenticate(SamlAuthenticator.java:48) at org.keycloak.adapters.saml.AbstractSamlAuthenticatorValve.executeAuthenticator(AbstractSamlAuthenticatorValve.java:224) at org.keycloak.adapters.saml.AbstractSamlAuthenticatorValve.invoke(AbstractSamlAuthenticatorValve.java:174) at org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:169) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:145) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:97) at org.jboss.as.web.sso.ClusteredSingleSignOn.invoke(ClusteredSingleSignOn.java:356) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:559) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:102) at com.redhat.container.redirect.RedirectToInternalValve.invoke(RedirectToInternalValve.java:61) at com.redhat.container.UTF8Valve.invoke(UTF8Valve.java:26) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:336) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:856) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:653) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:511) at org.jboss.threads.SimpleDirectExecutor.execute(SimpleDirectExecutor.java:33) at org.jboss.threads.QueueExecutor.runTask(QueueExecutor.java:808) at org.jboss.threads.QueueExecutor.access$100(QueueExecutor.java:45) at org.jboss.threads.QueueExecutor$Worker.run(QueueExecutor.java:849) at java.lang.Thread.run(Thread.java:745) at org.jboss.threads.JBossThread.run(JBossThread.java:122) -- PULKIT GUPTA SENIOR SOFTWARE APPLICATIONS ENGINEER Red Hat IN IT GBD <https://www.redhat.com/> Pune - India pulgupta(a)redhat.com T: +91-2066817536 <http://redhatemailsignature-marketing.itos.redhat.com/> IM: pulgupta <https://red.ht/sig>
