Description Antony Bowesman 2009-01-04 16:55:07 UTC
        at org.apache.poi.hpsf.extractor.HPSFPropertiesExtractor.getDocumentSummaryInformationText(HPSFPropertiesExtractor.java:59)
        at org.apache.poi.hpsf.extractor.HPSFPropertiesExtractor.getText(HPSFPropertiesExtractor.java:128)

It's caused by the following when trying to extract meta data properties from a Word document 

 POITextExtractor extractor = ExtractorFactory.createExtractor(new ByteArrayInputStream(raw));
 POITextExtractor mdExtractor = extractor.getMetadataTextExtractor();
 if (mdExtractor != null)
     String md = mdExtractor.getText();
     System.out.println("MD=:" + md);

and is caused because my Word document would not appear to have custom properties, therefore the getCustomProperties() method returns null in the following...

public String getDocumentSummaryInformationText() {
   // Now custom ones
   CustomProperties cps = dsi.getCustomProperties();
   Iterator keys = cps.keySet().iterator();
