Brian Stansberry commented on JBAS-7745:
----------------------------------------
You didn't answer my question: what Tomcat servlet examples? Please provide a link; I don't want to guess. :-) We have unit tests that test this kind of thing, so I want to see exactly what you are using.
Can you try this w/ AS 6.0.0.M2? There have been some changes in JBoss Cache and in the session manager integration with JBC since 5.1.0, some related to session metadata not being available. Although those were related to buddy replication, which it doesn't sound like you're using. Plus your description shows the failure happening on the 2nd request to the second cluster node, so it's not simple failover handling.
