| 44 | * The test creates an rmid with a special security manager. After |
| 45 | * rmid makes two registrations (which is greater than rmid's |
| 46 | * snapshotInterval) the security manager stops allowing rmid to write |
| 47 | * to update and snapshot log files in rmid's log directory. The Test |
| 48 | * registers an Activatable object twice with different group ids. |
| 49 | * The second registration will cause rmid to have to write to a |
| 50 | * LogFile (it causes a snapshot) and the security manager will not |
| 51 | * allow the file write to happen. The test makes sure that rmid |
| 52 | * shuts down in a graceful manner without any explicit request to do |
| 53 | * so. The test will not exit for 400 seconds if rmid does not exit |
| 54 | * (after that time, the test will fail). |
