    Description

      This might apply for more than just the footer. I only tested footer so don't
      know.

      compile and run this example and you will get an exception

      public class CliError
{
  public static void main(String[] args)
  {
    Options options = new Options();
    HelpFormatter formatter = new HelpFormatter();
    String footer = System.getProperty("line.separator")+"Hello world.";
    formatter.printHelp(80, "foobar", "", options, footer, true);
  }
}

      result is:

      java.lang.StringIndexOutOfBoundsException: String index out of range: -1
	at java.lang.String.charAt(String.java:582)
