EL表达式fn:endsWith函数的bug

jstl-1.2.jar

public static boolean endsWith(String input, String substring) {
  if (input == null)
    input = "";
  if (substring == null)
    substring = "";
  int index = input.indexOf(substring); // should be indexOf应该是lastIndexOf 才对
  if (index == -1)
    return false;
  if ((index == 0) && (substring.length() == 0))
    return true;
  return index == input.length() - substring.length();
}
