The 'ap05t001Subclass' class 43 * extends 'ap05t001Superclass' class and implements 44 * 'ap05t001Interface' interface. Each of the classes and 45 * the interface defines several static and instance fields 46 * of Object type but with dirrerent modifiers, i.e. private, 47 * public, protected or package-private. All these fields 48 * named as 'referreeXX' where XX is some decimal number. 49 * The test class initializes 'referrer' field and 50 * all 'referreeXX' fields. The last ones are assigned to 51 * the same Object instance. Then the tags are assigned 52 * to 'referrer', to Class instance of 'ap05t001Subclass' 53 * type and to the referred Object instance. 54 * Then the test agent runs IterateOverReachableObjects and 55 * IterateOverObjectsReachableFromObject. The test fails 56 * if defined jvmtiObjectReferenceCallback founds unexpected 57 * number of references between tagged objects. 58 * COMMENTS 59 * 60 * @library /vmTestbase 61 * /test/lib 62 * @run driver jdk.test.lib.FileInstaller . . 63 * @run main/othervm/native 64 * -agentlib:ap05t001=-waittime=5 65 * nsk.jvmti.scenarios.allocation.AP05.ap05t001 66 */ 67 68
