Hello all, It looks like Wildfly 10 changes a method interface in undertow and the keycloak is still linking against the old method. Going across a redirect, I get this exception: java.lang.NoSuchMethodError: io.undertow.server.Connectors.ungetRequestBytes(Lio/undertow/server/HttpServerExchange;[Lorg/xnio/Pooled;)V org.keycloak.adapters.undertow.SavedRequest.tryRestoreRequest(SavedRequest.java:112) org.keycloak.adapters.undertow.ServletSessionTokenStore.restoreRequest(ServletSessionTokenStore.java:119) org.keycloak.adapters.undertow.ServletSessionTokenStore.isCached(ServletSessionTokenStore.java:67) org.keycloak.adapters.RequestAuthenticator.authenticate(RequestAuthenticator.java:85) org.keycloak.adapters.undertow.AbstractUndertowKeycloakAuthMech.keycloakAuthenticate(AbstractUndertowKeycloakAuthMech.java:114) org.keycloak.adapters.undertow.ServletKeycloakAuthMech.authenticate(ServletKeycloakAuthMech.java:94) Looking at this commit: https://github.com/undertow-io/undertow/commit/b62c3f1efadeb86d94ed6577f5... the parameters changed type (from Pooled<ByteBuffer> to PooledByteBuffer). This is called from here: https://github.com/keycloak/keycloak/blob/master/integration/undertow/src... https://github.com/keycloak/keycloak/blob/master/integration/undertow/src... I'm guessing the call on 112 needs to make the new object type? Should I file a bug in the JIRA? Thanks, Kenn _______________________________________________ keycloak-user mailing list keycloak-user(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/keycloak-user
