为什么我在这个 lambda 上遇到编译错误

Question

In the following piece of code I am getting compilation error:

error: method method1 in class MyClass cannot be applied to given types;
                MyClass.method1(MyClass.method2());

however if I store MyClass in a variable at line 1, the error is gone

var myVar = MyClass.method2();
MyClass.method1(myVar); 

Here is the source:

class Test {
static void doSomething(Runnable c) {}

static void main() {
    doSomething(() -> {
        class MyClass {
            static void method1(MyClass myClass1) {}
            static MyClass method2() {return new MyClass();}
        }
        MyClass.method1(MyClass.method2());        //Line 1
    });
    }
} 

What is the possible reason for this?

Thanks!
