What is the use case of having static members inside a Method local inner class in Java?

Question

I was completely blown away after I made a static member in Method local inner class, I am wondering what might be its use case as the scope of MLIC member is only inside the method in which they are defined. Are MLIC's implicitly static? Then how am I able to access instance members from outer class?

class Test {
    int i = 8;

        //instance method
    void m() {
                //method local inner class  
        class I1{    
            static int x2 = 2; //static variable declaration

            public void main() {   
                System.out.println(i);  //outer class instance variable accessible
            }
            
            static void print() { //static method declaration
                System.out.println("I am a static method in MLIC");
            }
        }
        
        I1 i1 = new I1();
        i1.main();
        
        I1.print();
    }
}
