This document opens fine in Adobe Reader.While extracting page labels from 
getLabelsByPageIndices() i got the below exception

java.lang.ArrayIndexOutOfBoundsException: 3
        at 
org.apache.pdfbox.pdmodel.common.PDPageLabels$2.newLabel(PDPageLabels.java:218)

org.apache.pdfbox.pdmodel.common.PDPageLabels.computeLabels(PDPageLabels.java:252)
        at 
org.apache.pdfbox.pdmodel.common.PDPageLabels.getLabelsByPageIndices(PDPageLabels.java:214)

ORIGINAL CODE IN PDPageLabels.java

 public String[] getLabelsByPageIndices()
    {
        final String[] map = new String[doc.getNumberOfPages()];
        computeLabels(new LabelHandler()
        {
            public void newLabel(int pageIndex, String label)
            {
              
                map[pageIndex] = label;
              
            }
        });
        return map;
    }

It works fine with the below modified code in PDPageLabels.java

MODIFIED CODE IN PDPageLabels.java


 public String[] getLabelsByPageIndices()
    {
        final String[] map = new String[doc.getNumberOfPages()];
        computeLabels(new LabelHandler()
        {
            public void newLabel(int pageIndex, String label)
            {
               if(pageIndex < doc.getNumberOfPages()){
                map[pageIndex] = label;
               }
            }
        });
        return map;
    }
