    31  * DESCRIPTION

    32  *     Test calls a boostrap and a target methods via InvokeDynamic call, monitoring that

    33  *     a method in the debuggee class (Dummy0.redefineNow()) is called (monitoring is done

    34  *     via MethodEntry event). At this moment, Dummy0 class is redefined using RedefineClasses

    35  *     function to Dummy1 class (in its classfile every occurence of "Dummy1" is replaced with

    36  *     "Dummy0") and PopFrame function is called to reenter the method.

    37  *     The test verifies that when class is redefined in a target method (at that moment,

    38  *     the call site is linked) and frame is popped, the new target method is executed and

    39  *     the site is relinked.
