Source format automatically removes braces from "else" statement with "if-else" inside. I'm aware that it doesn't change execution flow, but anyway it shouldn't happen.

Testcase:

    public void demo(boolean a, boolean b) {
        if (a) {
            if (b) {
                System.out.println("a AND b");
            } else {
                System.out.println("a AND NOT b");
            }
        } else {
            // a is false
            if (b) {
                System.out.println("NOT a AND b");
            } else {
                System.out.println("NOT a AND NOT b");
            }
        }
    }

After format:

    public void demo(boolean a, boolean b) {
        if (a) {
            if (b) {
                System.out.println("a AND b");
            } else {
                System.out.println("a AND NOT b");
            }
        } else // a is false
        if (b) {
            System.out.println("NOT a AND b");
        } else {
            System.out.println("NOT a AND NOT b");
        }
    }

The code after the format is harder to read and it's not fit our coding style.
