为什么 NativeMethodAccessorImpl 声明 InvocationTargetException

Why NativeMethodAccessorImpl declare InvocationTargetException

NativeMethodAccessorImpl invoke method 声明它可以抛出 IllegalArgumentExceptionInvocationTargetException

public Object invoke(Object obj, Object[] args)
    throws IllegalArgumentException, InvocationTargetException
{
    // We can't inflate methods belonging to vm-anonymous classes because
    // that kind of class can't be referred to by name, hence can't be
    // found from the generated bytecode.
    if (++numInvocations > ReflectionFactory.inflationThreshold()
            && !ReflectUtil.isVMAnonymousClass(method.getDeclaringClass())) {
        MethodAccessorImpl acc = (MethodAccessorImpl)
            new MethodAccessorGenerator().
                generateMethod(method.getDeclaringClass(),
                               method.getName(),
                               method.getParameterTypes(),
                               method.getReturnType(),
                               method.getExceptionTypes(),
                               method.getModifiers());
        parent.setDelegate(acc);
    }
    return invoke0(method, obj, args);
}
private static native Object invoke0(Method m, Object obj, Object[] args);

本机方法 在某些情况下,例如

Exception in thread "main" java.lang.IllegalArgumentException: argument type mismatch
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

但是我没有看到任何抛出 InvocationTargetException checked exception

的选项

InvocationTargetException 可以被本机方法 invoke0 抛出(不声明异常)吗?

或者 InvocationTargetException 是否因为方法签名 backward/future 兼容性而保留?

invoke0 可以抛出 InvocationTargetException:

Exception in Application start method
java.lang.reflect.InvocationTargetException
        at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
        at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

例如当找不到 FXML 资源文件时。
