This configuration comes from investigating https://bugzilla.redhat.com/show_bug.cgi?id=1122662. The configuration uses a shared JDBC cache store configuration with a different prefix set for each node in the cluster. Each node in the cluster writes a different table in the database which doesn't work very well when preload is used. (See https://bugzilla.redhat.com/show_bug.cgi?id=1122662#c11 for an example of the problem.) Infinispan expects that one node in the cluster has access to all of the data in the cluster in this situation, and all entries on the node will be inaccessible if a node fails.

If Infinispan detects this configuration, then a warning message should be logged.
