[Bug][Extract Method Refactoring] Extract method refactoring for Generics in Local Class produces uncompilable program

[RETester66]

Steps to reproduce

1. Create a class named A:

public class A {
    void foo(Integer value) {
        class Local<T> {
            void bar(T param) {
                Runnable runnable = () -> {
                    System.out.println(param); // Extract method on this statement
                };
            }
        }
    }
}

2. Select the statement System.out.println(param); like I comment. Then, right click -> Refactor -> Extract Method. Choose the Destination Type as A, the configuration to extract this method like following, click ok:

The program is successfully refactored without any warning or exception. The refactored program is following, which contains syntax error:

public class A {
    void foo(Integer value) {
        class Local<T> {
            void bar(T param) {
                Runnable runnable = () -> {
                    extracted(param); // Extract method on this statement
                };
            }
        }
    }

	private void extracted(T param) {// syntax error
		System.out.println(param);
	}
}
