Wrong documentation for delayed message

[fjmpaez911]

In the chapter of Reference Manual said:

properties.setXDelay(15000);

when this method doesn't exists.

The correct method is (setDelay):

/**

• Set the x-delay header.
• @param delay the delay.
• @SInCE 1.6
  */
  public void setDelay(Integer delay) {
  if (delay == null || delay < 0) {
  this.headers.remove(X_DELAY);
  }
  else {
  this.headers.put(X_DELAY, delay);
  }
  }
