A register method of a Finalizer class is modified to cause the register method to pass, to a specified programmatic mechanism, an object that was passed to the register method; modifying a finalize method of a class of the object to (a) cause the object to invoke a first method of the programmatic mechanism when the finalize method is invoked by a virtual machine and (b) prevent a remainder of the finalize method from completing under specified conditions, thereby causing a call to the finalize method to remain undispatched. The first method, when invoked, (a) adds, to the object, a reference that temporarily prevents the object from being deleted and (b) records an identifier of the object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ensuring determinism during programmatic replay in a virtual machine","description":"A replay core ensures that references to objects are removed at the same relative times and in the same relative order within a program's execution during both record time and replay time.
