"convertRawBytesToEscherRecords()" Line 99: convertToEscherRecords(0, rawData.length, rawData); ^ |- Not checked for null, causes NPE To reproduce: 1. Create drawing patriarch HSSFPatriarch patr = sheet.createDrawingPatriarch(); 2. Use patriarch HSSFClientAnchor anchor = new HSSFClientAnchor(0,0, 600,245, (short)1,1, (short)1,2); anchor.setAnchorType(3); patr.createPicture(anchor, loadImage(LOGO_PATH, HSSFWorkbook.PICTURE_TYPE_JPEG)); 3. Try to re-use patriarch later HSSFPatriarch existingPatr = sheet.getDrawingPatriarch(); 4. Kaboom.
