java - System.out.print('\r') が機能しない

Question

奇妙\rな理由で動作しません。行の先頭には戻りません。

char[] animationChars = new char[] {'|', '/', '-', '\\'};

public Main() {

    for (int i = 0; i < 100; i++) {
        System.out.print("Processing: " + i + "% " + animationChars[i % 4] + '\r');

        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

}
