| * DESCRIPTION |
| * The test implements AP05 scenario of test plan for Allocation |
| * Profiling. |
| * The test checks the following common assertion from specs |
| * of IterateOverReachableObjects and |
| * IterateOverObjectsReachableFromObject: |
| * The callback (jvmtiObjectReferenceCallback) is called |
| * exactly once for each reference from a referrer; |
| * this is true even if there are reference cycles or |
| * multiple paths to the referrer. |
| * The test class 'ap05t001' defines self-typed instance |
| * 'referree' field. The test class assignes 'referree' |
| * field to new instance and assignes 'referree' field |
| * of new instance to current instance 'ap05t001' class. |
| * Thus the test class creates reference cycle. |
| * Then tags are set for 'referree' and 'this' instances. |
| * Then the test agent runs IterateOverReachableObjects and |
| * IterateOverObjectsReachableFromObject. The test fails |
| * if defined jvmtiObjectReferenceCallback is called not |
| * once for each reference of created reference cycle. |
