| /** |
| * This test tests the scenario whereby a register interest has been called before the region has |
| * been created. After that if a region is created and the new region gets data from another |
| * mirrored node, it should propagate to the client which registered interest before the region was |
| * created. |
| * |
| * The scenario is: - 2 servers 2 clients - client1 connected to server1 - client2 connected to |
| * server2 - client2 registers interest for region1 on server2 before region1 is created - data is |
| * put on region1 in server1 - mirrored region1 is created on server2 - data will come to region1 on |
| * server2 via GII - data should be sent to client2 |
