Remote store config errors in AS7

When remote-store is configured in domain.xml, on server startup following errors :-

[Server:server-one] 17:00:00,889 ERROR [org.jboss.msc.service.fail] (pool-13-thread-1) MSC00001: Failed to start service jboss.infinispan.web.repl: org.jboss.msc.servic

[Server:server-one] Caused by: java.lang.ClassNotFoundException: org.infinispan.client.hotrod.impl.transport.tcp.TcpTransportFactory

Looks like some issue in locating the jar which contains this class file. I could resolve this issue by :-

Adding the following :-
<module name="org.infinispan.client.hotrod"/>

in %JBOSS_HOME%/modules/org/infinispan/main/module.xml

This seems to be a bug as it should work out of the box.
