Automatic program repair in plugin

[aosen-xiong]

For a buggy code snippet like below,

public class Greeting {
    
    public static void greet(String name) {
        System.out.println("Hello, " + name.trim());
    }

    public static void main(String[] args) {
        greet(null);  // This will throw a NullPointerException
    }
}

can we have some features to automatic generate code patch like

public class Greeting {
    
    public static void greet(@NonNull String name) {
        System.out.println("Hello, " + name.trim());
    }

    public static void main(String[] args) {
        String name = null;
        
        if (name != null) {
            greet(name);  // Safe now!
        } else {
            System.out.println("Name is not provided.");
        }
    }
}

I think this will be helpful for developers are using the plugin.
