docs: Attempts to get a new socket connection to the given host within the given time limit.
  <p>
  This method employs several techniques to circumvent the limitations of older JREs that
  do not support connect timeout. When running in JRE 1.4 or above reflection is used to
  call Socket#connect(SocketAddress endpoint, int timeout) method. When executing in older
  JREs a controller thread is executed. The controller thread attempts to create a new socket
  within the given limit of time. If socket constructor does not return until the timeout
  expires, the controller terminates and throws an {@link ConnectTimeoutException}

  @throws IOException if an I/O error occurs while creating the socket
