If 0 is specified, objects in the JavaHeap that are referenced by objects in an Explicit memory block will be transferred to the Explicit memory block when full GC occurs.
If 1 is specified, objects in the JavaHeap that are referenced by objects in an Explicit memory block will not be transferred to the Explicit memory block even when full GC occurs. The objects in the New area are transferred to the Tenured area.
