      Wrapper method for get() methods which require some specific value format. This catches any NumberFormatException or IllegalArgumentException and re-raises it with the incorrectly configured key in the exception message.
      Parameters:
      key - (undocumented)
      getValue - (undocumented)
      Returns:
      (undocumented)
