Stack overflow error on word graph creation, using text with multiple spaces about jinsect HOT 2 CLOSED

In DocumentWordGraph we utilize the utils.splitToWords function, to split the text to words.
There we used a RegExp to split based on punctuation and spaces:
Originally it was
String [] sRes = sStr.split("(\\s|\\p{Punct})+");
In the specific files, there exist too many whitespace characters. Can be fixed by simply ignoring full groups of whitespace/punctuation as follows:
String [] sRes = sStr.split("(\\s+|\\p{Punct}+)+");

As a temporary solution, you can simply replace all multi-whitespace sequences in the text with a single space, before feeding it to the graph:

       String text = utils.loadFileToString("inputText.txt");
        text = text.replaceAll("\\s+", " ");
        DocumentWordGraph wg = new DocumentWordGraph();
        wg.setDataString(text); // stack overflow error - no longer here! :)
        
        System.out.println(wg.getGraphLevel(0));

I will try to update the utils class appropriately... sometime soon.
