| * @summary converted from VM Testbase nsk/jvmti/scenarios/allocation/AP04/ap04t002. |

| * DESCRIPTION |
| * The test implements AP04 scenario of test plan for Allocation |
| * Profiling. |
| * The test checks the following assertion of spec of heap |
| * iteration function: |
| * During the execution of this function the state of the heap |
| * does not change: no objects are allocated, no objects are |
| * garbage collected, and the state of objects (including held |
| * values) does not change. As a result, threads executing Java |
| * programming language code, threads attempting to resume the |
| * execution of Java programming language code, and threads |
| * attempting to execute JNI functions are typically stalled. |
| * The test class 'ap04t002' contains self-typed array field |
| * 'root' which is initialized in preliminary phase of test |
| * cases. Each element of 'root' array is tagged. |
| * Then an auxiliary application thread has started which |
| * runs one of the heap iteration function. After receiving a |
| * notification on start of auxuliary thread, the main thread of |
| * test application assignes new value to int field 'modified' |
| * in a 'while' cycle until completion of heap iteration. |
| * The test agent sets enables FieldModification event. The test |
| * fails if any FieldModification event was received during heap |
| * iteration. |
| * COMMENTS |
| * Test fixed according to test bug: |
| * 5050527 nsk/jvmti/scenarios/allocation/AP04/ap04t002 has timing issue |
