      Description

      Velocity has a feature that allows calling List methods on arrays.
      I tried doing that on a String array.

      #if ($data.viewOnlineLinkLocales.empty)
      Hello
      #end
      

      "data" has a method:

          public List<String> getViewOnlineLinkLocales() {
              String localeStr = getProperty(LOCALES);
              if (localeStr == null) {
                  return new String[0];
              }
              return StringUtils..split(",");
          }
      

      When I try this for localeStr = null, the "empty" is returning false. On the other hand when I replace it with "isEmpty()" it correctly returns true.
