java - resolveClass 不解析符号引用

Question

JLS 说resolveClass 方法应该验证所有符号链接(symbolic link)

This specification allows an implementation flexibility as to when linking activities (and, because of recursion, loading) take place, provided that the semantics of the Java programming language are respected, that a class or interface is completely verified and prepared before it is initialized, and that errors detected during linkage are thrown at a point in the program where some action is taken by the program that might require linkage to the class or interface involved in the error.

因此，我尝试创建引用第一个项目中另一个类的类 T，并使用自定义类加载器加载类 T 但不加载另一个引用的类来创建第二个项目。

public class T {
    public static AnotherClass field = new AnotherClass();
}

public class AnonClassLoader extends ClassLoader {

    public Class findClass(String str) {
        byte[] bytes = new byte[0];
        try {
            bytes = Files.readAllBytes(Paths.get(str));
        } catch (IOException e) {
            e.printStackTrace();
        }
        Class<?> aClass = defineClass(null, bytes, 0, bytes.length);
        return aClass;
    }

    public static void main(String[] args) throws IOException, NoSuchMethodException, IllegalAccessException,
        InvocationTargetException, InstantiationException, ClassNotFoundException {
        AnonClassLoader anonClassLoader = new AnonClassLoader();
        Class<?> aClass = anonClassLoader.loadClass("/Users/root/IdeaProjects/untitled/T.class", true);
        System.out.println(aClass.getName());
    }
}

所以我期望尽快得到NoClassDefFound，但实际结果 - 没有抛出错误，类解析成功

所以，根据错误 ID:JDK-8057777 Cleanup of old and unused VM interfaces热点没有静态解析。

同时，在 hotspot jdk 8原生函数没有实现
