Some more information:

Using this main-function:

    public static void main(String[] args) {
                for (int i = 0; i < 10000; ++i)
                {
                        {
                                Options opt = new Options("Queens");
                                opt.size = 6;
                                opt.gui = true;
                                opt.parse(args);

                                Queens queens = new Queens(opt.size);
                                opt.doSearch(queens);
                        }
                        System.out.println("Ran iteration " +
String.valueOf(i));

                        try
                        {
                                System.gc();
                                Thread.sleep(1);
                        }
                        catch (Exception e)
                        {
                                return;
                        }
                }
    }

makes the program work again (probably by luck). My interpretation is that the
problem lies with swig or JNI and its interaction with the java memory system.
