| * DESCRIPTION |
| * This JVMTI test exercises JVMTI heap function IterateOverHeap(). |
| * This test checks that IterateOverHeap() function with |
| * JVMTI_HEAP_OBJECT_UNTAGGED filter iterates over all untagged |
| * objects in the heap even is they are not reachable; |
| * and passes correct values to the callback. |
| * The test creates and tags the following tested objects: |
| * root object - root object with 2 chains |
| * chain of reachable objects - tagged/untagged objects to be iterated |
| * chain of unreachable objects - tagged objects to be iterated or GC'ed |
| * The test marks reachable objects with positive tags and |
| * unreachable objects with negative tags. |
| * Also each object in reachable chain is marked with zero tag |
| * (i.e., left untagged). |
| * Unreachable objects are monitored for OBJECT_FREE event to know |
| * if they were not iterated because of garbage collected. |
| * Local JNI references are explicitely deleted to ensure them |
| * not to affect the objects' reachability. |
| * The test supports the following special options: |
| * objects=<number> |
| * - number of objects in each objects chain |
| * info=[none|all|objref|stackref|heaproot|heapobj|tagged] |
| * - print trace message for each invocation of particular callback |
| * COMMENTS |
| * Fixed according to 4960375 bug. |
| * The test updated to match new JVMTI spec 0.2.94. |
| * Fixed the 5005389 bug. |
