What steps will reproduce the problem?
1. Run the attached unit test against the attached Word 97 document.

I found this issue too. I've worked around it by adding sanity checks to the 
bounds.
See the code below - the stuff I added is commented

    for (int x = 0; x < textRuns.size(); x++)
    {
      CHPX chpx = (CHPX)textRuns.get(x);
      if (!isDeleted(chpx.getGrpprl()))
      {
        /**
         * Begin Sanity checks
         *      1. If end > length force end == length
         *      2. if start > end or start > length, skip
         */
        int end = (chpx.getEnd()>allTxt.length()) ? allTxt.length() : chpx.getEnd();
        if ((chpx.getStart()>chpx.getEnd()) || (chpx.getStart()>allTxt.length())) continue;
        /**
         * End sanity checks
         */
        String str = allTxt.substring(chpx.getStart(), end);
        scrubber.append(stringWriter, str);
      }
    }
