Tomcat8 standalone : jvmRoute not added to jessionid cookie when generated as UUID by JvmRouteFactory ----------------------------------------------------------------------------------------------------- Key: MODCLUSTER-469 URL: https://issues.jboss.org/browse/MODCLUSTER-469 Project: mod_cluster Issue Type: Bug Components: Core & Container Integration (Java) Affects Versions: 1.3.1.Final, 1.4.0.Alpha1 Environment: Apache 2.4, ModCluster 1.3.1, Tomcat 8.0 standalone Reporter: Eric Vernier Assignee: Radoslav Husar Fix For: 1.4.0.Alpha2 If jvmRoute attribute is not set in server.xml on engine element, ModClusterService generates a jvmRoute (UUID). This UUID is not added in the value of the cookie "jsessionid", so the sticky session doesn't work. When the jvmRoute is defined in the server.xml all works fine. I known no much about lifecyle in Catalina, but my feeling is that ModClusterService generates the jvmRoute (with JvmRouteFactory) after the creation of SessionIdGenerator by the org.apache.catalina.Manager. When ModClusterService injects the generated jvmRoute it's too, the SessionIdGenerator is already created.
