SpannableStringBuilder append() NullPointerException

public SpannableStringBuilder append(CharSequence text) {
    int length = length();
    return replace(length, length, text, 0, text.length());
}

SpannableStringBuilder source code append() function doesn't avoid NullPointerException ?? If text is null, append() function definitely throw NullPointerException . It's easily be forgotten to check every case if text is null. For example the text may from the server. Anyone has a better idea for SpannableStringBuilder append() function to avoid npe?
