[Bug][Inline Method Refactoring] Inline Method refactoring for Multiple anonymous classes interacting within the method to be inlined produces uncompilable program

[RETester66]

Steps to reproduce

1. The input progam is following:

public class A {
    int data = 100;

    void superClassMethod() {
        System.out.println("Data: " + data);
    }

    static void callingMethod(A instance) {
        instance.methodToBeInlined(); // inline call to methodToBeInlined()
    }

    void methodToBeInlined() {
        Runnable r1 = new Runnable() {
            public void run() {
                data += 20;
            }
        };

        Runnable r2 = new Runnable() {
            public void run() {
                A.this.superClassMethod();
                r1.run();
            }
        };

        r2.run();
    }
}

2. Left click methodToBeInlined() in instance.methodToBeInlined(); like I comment. Then, right click -> Refactor -> Inline. Use the default configuration to inline 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 {
    int data = 100;

    void superClassMethod() {
        System.out.println("Data: " + data);
    }

    static void callingMethod(A instance) {
        Runnable r1 = instance.new Runnable() {// syntax error
		    public void run() {
		        instance.data += 20;
		    }
		};
		
		Runnable r2 = instance.new Runnable() {// syntax error
		    public void run() {
		        A.this.superClassMethod();
		        r1.run();
		    }
		};
		
		r2.run(); // inline call to methodToBeInlined()
    }

    void methodToBeInlined() {
        Runnable r1 = new Runnable() {
            public void run() {
                data += 20;
            }
        };

        Runnable r2 = new Runnable() {
            public void run() {
                A.this.superClassMethod();
                r1.run();
            }
        };

        r2.run();
    }
}
