Description of problem: the module "modules/org/infinispan/client/hotrod/jdg-6.4/" contains the same jar but different dependencies. This will be overwritten if both EAP modules (jboss-datagrid-6.4.0-eap-modules-library | jboss-datagrid-6.4.0-eap-modules-remote-java-client) are installed. This is error prone as the dependencies depend on the installation order and and also it is not possible to use both modules at the same time if there are different application deployed which use both modes.
