Array Index Issue while running Demo

[OGalOz]

I got this error while running the demo through a Docker container:

A possible fix is to replace the code in org.cellocad.MIT.dnacompiler.PlasmidUtil.setTxnUnits to the following:

        else {
        boolean f1 = g.getChildren().size() > 0 && (
		g.system.equals("CRISPRi") || g.getChildren().get(0).system.equals("CRISPRi") ||
		g.system.equals("Ecoligenome") || g.getChildren().get(0).system.equals("Ecoligenome") ||
		g.system.equals("Yeast") || g.getChildren().get(0).system.equals("Yeast")
	);

	boolean f2 = g.getChildren().size() > 1 && (
		g.getChildren().get(1).system.equals("Ecoligenome") ||
		g.getChildren().get(1).system.equals("Yeast")
	);

	/*
	   if(g.system.equals("CRISPRi") || g.getChildren().get(0).system.equals("CRISPRi")
	   || g.system.equals("Ecoligenome") || g.getChildren().get(0).system.equals("Ecoligenome") || g.getChildren().get(1).system.equals("Ecoligenome")
	   || g.system.equals("Yeast") || g.getChildren().get(0).system.equals("Yeast") || g.getChildren().get(1).system.equals("Yeast")) {
	   */
	if(f1 || f2) {

                for(String var: g.get_variable_names()) {

                    for(Wire w: g.get_variable_wires().get(var)) {
                        ArrayList<Part> txn_unit = new ArrayList<>();

                        txn_unit.add(w.to.get_regulable_promoter());

                        ArrayList<Part> expression_cassette = g.get_downstream_parts().get(var);

                        txn_unit.addAll(expression_cassette);

                        g.get_txn_units().add(txn_unit);
                    }

                }

The original conditional statement is commented out but left there to show where the change occurs.
