    • A method, computer program product, and system for non-blocking dynamic update of statically-typed class-based object-oriented software executing as byte-code on a virtual machine within an actively running computer system is provided. A set of objects instantiated from an existing module or multiple modules (identifiable collections of application resources and class definitions in the form of byte-code representations) is ready for execution on a virtual machine in an actively running computer system. New versions of one or more modules corresponding to those already loaded into the actively running virtual machine are dynamically loaded into the virtual machine for the purpose of updating the running software. The class definitions within the loaded modules are prepared for dynamic update by inserting byte-code that enables; transparent state transfer and shared object identity between objects of a former version and the new version of a class.
    • 提供了一种用于在主动运行的计算机系统内的虚拟机上作为字节码执行的静态类基于类的面向对象软件的非阻塞动态更新的方法,计算机程序产品和系统。 从现有模块或多个模块(可识别的应用程序资源集合和字节码表示形式的类定义)实例化的一组对象可以在主动运行的计算机系统中的虚拟机上执行。 与已经加载到主动运行的虚拟机中的那些对应的一个或多个模块的新版本被动态地加载到虚拟机中以便更新正在运行的软件。 加载的模块中的类定义通过插入启用的字节码来准备动态更新; 透明状态传输以及旧版本的对象与新版本的类之间的共享对象标识。
