 * @summary converted from VM Testbase nsk/jvmti/AttachOnDemand/attach002.
 * VM Testbase keywords: [jpda, jvmti, noras, feature_282, vm6, jdk]
 * 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:
 *         - loaded agent can get capabilities 'generate_all_class_hook_events' and 'can_redefine_classes'
 *         - agent receives events ClassFileLoadHook, ClassLoad, ClassPepare for the class loaded by the target
 *         application
 *         - agent can redefine class loaded by the target application from the ClassLoad event handler and
 *         agent receives ClassFileLoadHook after class redefinition
 *         - after class redefinition target application checks that redefinition really had effect
