* VM Testbase readme:
* DESCRIPTION
* This test is designed to check, whether the invocation order of retransformation agents
* are correct or not. Transformation capable and incapable agents are mixed together.
* The specification defines the following behavior as correct:
* When classes are initially loaded or when they are redefined, the initial class file
* bytes can be transformed with the ClassFileLoadHook event. This function reruns the
* transformation process (whether or not a transformation has previously occurred).
* This retransformation follows these steps:
* * starting from the initial class file bytes
* * for each retransformation incapable agent which received a ClassFileLoadHook
* event during the previous load or redefine, the bytes it returned (via the
* new_class_data parameter) are reused as the output of the transformation;
* note that this is equivalent to reapplying the previous transformation,
* unaltered. except that the ClassFileLoadHook event is not sent to these agents
* * for each retransformation capable agent, the ClassFileLoadHook event is sent, allowing a new transformation to be applied
* * the transformed class file bytes are installed as the new definition of the class
* COMMENTS
