Raise a feature request or better yet provide a patch. It looks like a trivial change to me in org.jboss.resource.connectionmanager.InternalManagedConnectionPool | - throw new ResourceException("No ManagedConnections available within configured blocking timeout ( " | + poolParams.blockingTimeout + " [ms] )"); | + throw new ResourceException(jcmp.getPoolJndiName() + " - no ManagedConnections available within configured blocking timeout ( " | + poolParams.blockingTimeout + " [ms] )"); | I guess there's other places that would benefit from it as well?
