DocProcessor is not detecting missing params

So I tried using the DocProcessor.process method on the MathUtils class but it doesn't show messages for missing parameters, even tough there are some missing in the class.

public class DocProcessor {
  public static boolean process(Class clazz) {
    // ...
    // Does the number of items in param descriptions match
    // the number of actual parameters?
    int numMissing = getNumMissingParams(method, doc);
    if (numMissing > 0) {
      String message = "%n\t\t=> Missing %s parameter description(s)";
      System.out.printf(message, numMissing);
  private static int getNumMissingParams(Method method, Doc doc) {
    /* Check if the number of parameter descriptions in the annotation
       is less than the method's parameter count */
    int actualParamCount = method.getParameterCount();
    int annotatedParamCount = doc.params().length;
    // Calculate the number of missing parameter descriptions
    return actualParamCount - annotatedParamCount;
