Keycloak Version 1.7.0 We get this exception: ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/].[AppName]] Servlet.service() for servlet NasDefault threw exception: java.lang.RuntimeException: This method is not supported in a restored authenticated request at org.keycloak.adapters.servlet.FilterSessionStore$1.getDateHeader(FilterSessionStore.java:178) [:1.7.0.CR1] at org.apache.catalina.servlets.DefaultServlet.checkIfModifiedSince(DefaultServlet.java:1731) [:] at org.apache.catalina.servlets.DefaultServlet.checkIfHeaders(DefaultServlet.java:608) [:] at org.apache.catalina.servlets.DefaultServlet.serveResource(DefaultServlet.java:714) [:] at org.apache.catalina.servlets.DefaultServlet.doGet(DefaultServlet.java:368) [:] at javax.servlet.http.HttpServlet.service(HttpServlet.java:734) [:1.0.0.Final] at javax.servlet.http.HttpServlet.service(HttpServlet.java:847) [:1.0.0.Final] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:324) [:] at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:242) [:] ...
