 * VM Testbase keywords: [jpda, jvmti, noras, feature_282, vm6, jdk, nonconcurrent]
 * VM Testbase readme:
 * Description :
 *     Test tries to load jvmti agent to the VM after the VM has started using
 *     Attach API (com.sun.tools.attach).
 *     Test is based on the nsk.share.aod framework. In the terms of this framework
 *     java application running in the VM where agent is loaded to is called 'target application'.
 *     Test performs following checks:
 *         - agent can get capabilities 'can_tag_objects', 'can_generate_object_free_events',
 *         'can_generate_vm_object_alloc_events'
 *         - agent receives VMObjectAlloc events for objects created using Class.newInstance
 *         - agent can tag object (JVMTI function SetTag)
 *         - agent receives ObjectFree events for tagged objects
 *         (in this test target application creates objects using Class.newInstance (generates events
 *         VMObjectAlloc) and provokes collection of these objects (generates events ObjectFree))
