We use picketlink 2.7.0 Final on Wildfly 8.0.0.Final in HA mode. With the start of using this PicketLink version we get next exception in replication of session: org.infinispan.commons.marshall.NotSerializableException: org.picketlink.config.http.PathConfiguration. We think this relates to PLINK-687 issues which was solved for 2.7.0.Final
