Steps to reproduce

  1. Create a class named A:
public class A<T> {
    void superMethod(T t) {}
}

  1. Then, create a class named B:
public class B extends A<String> {
    void methodToBeInlined() {
        super.superMethod("Hello");
    }

    static void callingMethod(B instance) {
        instance.methodToBeInlined(); // attempt to inline this call
    }
}
  1. Left click methodToBeInlined() in instance.methodToBeInlined(); like I comment in class B. Then, right click -> Refactor -> Inline. Use 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<T> {
    void superMethod(T t) {}
}

public class B extends A<String> {
    void methodToBeInlined() {
        super.superMethod("Hello");
    }

    static void callingMethod(B instance) {
        super.superMethod("Hello"); // syntax error
    }
}
