    • The techniques and mechanisms described herein are directed at sharing objects between applications executing in a virtual runtime environment. The techniques include compiling a cpu-independent file to create executable instructions that are associated with an application that is executable in a virtual runtime environment. A constructor associated with a shareable class defined within the cpu-independent file is executed to create an instance of a shareable object. The shareable object is then persisted in a manner such that other applications executing in the virtual runtime environment may access the shareable object. The technique may be performed during pre-JIT compilation or just-in-time compilation of the cpu-independent file. The execution of the constructor is performed at a restricted security level that prevents access to changeable information when generating static data for the static members of the shareable object.
    • 本文描述的技术和机制针对在虚拟运行时环境中执行的应用之间共享对象。 这些技术包括编译独立于cpu的文件,以创建与在虚拟运行时环境中可执行的应用程序相关联的可执行指令。 执行与与cpu无关文件中定义的可共享类相关联的构造函数,以创建可共享对象的实例。 然后可共享对象以使得在虚拟运行时环境中执行的其他应用程序可以访问可共享对象的方式被保持。 该技术可以在JIT编译期间执行,也可以及时编译不依赖cpu的文件。 构造函数的执行是在受限的安全级别执行的,该级别在为可共享对象的静态成员生成静态数据时阻止访问可更改的信息。

    • A system and method for mitigating problems associated with automatic execution of initialization code is provided. The system includes an initialization method activator that can call a class initialization method at a pre-determined execution point. The system also includes a deadlock analyzer that can determine whether calling the initialization method will create a deadlock, and, if a deadlock is detected that can resolve such a deadlock. The system also includes a semantic analyzing component that can analyze a semantic type associated with the initialization method and a domain uniqueness analyzer that can analyze the uniqueness of the domain with which the class will interact, to facilitate determining where to place code that will check whether a class is initialized, and if the class is not initialized that will invoke the class initializing method.
    • 提供了一种减轻与自动执行初始化代码相关的问题的系统和方法。 该系统包括可以在预定执行点调用类初始化方法的初始化方法激活器。 该系统还包括一个死锁分析器,可以确定调用初始化方法是否会产生死锁,并且如果检测到可以解决这种死锁的死锁。 该系统还包括可以分析与初始化方法相关联的语义类型的语义分析组件和可以分析类将与之交互的域的唯一性的域唯一性分析器,以便于确定在哪里放置将检查是否 一个类被初始化,如果类没有被初始化,这将调用类初始化方法。
