* @summary converted from VM Testbase nsk/jvmti/IterateOverReachableObjects/iterreachobj001.
* VM Testbase keywords: [quick, jpda, jvmti, noras]
* VM Testbase readme:
* DESCRIPTION
* This JVMTI test exercises JVMTI heap function IterateOverReachableObjects().
* This tests checks that IterateOverReachableObjects() function
* iterates over all tagged objects reachable from the tested root object
* and does not iterate over unreachable tagged objects,
* Also the test checks that IterateOverReachableObjects() pass
* not NULL tag pointer to the callback function.
* The test creates and tags the following tested objects:
* root object - root object with 2 chains
* chain of reachable objects - tagged objects to be iterated
* chain of unreachable objects - tagged objects to be not iterated
* The test marks reachable objects with positive tags and
* unreachable objects with negative tags.
* 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]
* - 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.
