The real reason for this is probably the user has installed jboss messaging in a non clustered app server configuration (e.g. like default), but has set clustered=true in the config file.

If clustering is required, then jbm must be installed in a clustered app server config where jgroups is already available.

There should be no need to copy jgroups.jar if the installation was performed correctly.
