    32  * DESCRIPTION

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

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

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

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

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

    38  *     The test verifies that:

    39  *     - When class is redefined in bootstrap method frame, a new bootstrap method is called after PopFrame()

    40  *     CR 6929027
