Research direction
Start by reproducing step 7 and reviewing the cluster-formation output from Terminal A and Terminal B. Inspect the Infinispan/JGroups configuration for the WeatherApp channel and compare the reported cluster views and physical addresses. Done means both terminals join the same cluster and cluster creation proceeds past the waiting state.
