Session attribute lost issue with the ATTRIBUTE replication-granularity + non-BATCH cache in a failover scenario in JBoss EAP 7

Issue

• Session attributes lost issue happens with the configuration using the ATTRIBUTE replication-granularity + non-BATCH cache in a failover scenario in JBoss EAP 7.
• A newly created session attribute after failover is lost in the subsequent session.getAttribute() invocations during the same request processing.

• This issue happens When I have a web application which has the "ATTRIBUTE" replication granularity in jboss-web.xml:

  <?xml version="1.0" encoding="UTF-8"?>
  <jboss-web
          version="7.1"
          xmlns="http://www.jboss.com/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee http://www.jboss.org/schema/jbossas/jboss-web_7_1.xsd">
      <replication-config>
          <replication-granularity>ATTRIBUTE</replication-granularity>
      </replication-config>
  </jboss-web>
  

  and <transaction mode="BATCH"/> is disabled for the "web" cache in infinispan subsystem like this knowledge article:

      <subsystem xmlns="urn:jboss:domain:infinispan:7.0">
          ...
          <cache-container name="web" default-cache="dist" module="org.wildfly.clustering.web.infinispan">
              <transport lock-timeout="60000"/>
              <distributed-cache name="dist">
                  <!-- <locking isolation="REPEATABLE_READ"/> -->
                  <!-- <transaction mode="BATCH"/> -->
                  <file-store/>
              </distributed-cache>
          </cache-container>
          ...
      </subsystem>
