> When users create their own JGroups configuration file and name it the same way as default configuration files (jgroups-udp.xml / jgroups-tcp-xml / jgroups-ec2.xml), they might not be visible to the user application as they're shadowed by the default configuration files.
> Proposed solution:
> * place current jgroups configuration files into META-INF/configs folder (this folder doesn't have to have an obscure name such as "_internal" because of the following two points which complement the solution)
> * define order in which the config files are read by class loader (i.e. first scan user application, then path under META-INF/configs)
> * when Infinispan is started, log the path to the configuration file used, e.g.:
> {code}
