Summary: HSSFSheet instance, getDrawingPatriarch
NullPointerException
Product: POI
Version: 3.0
Platform: PC
OS/Version: Windows Vista
Status: NEW
Severity: normal
Priority: P2
Component: HSSF
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
In POI 3.0.2-FINAL:
After creating a drawing patriarch on a sheet, retrieving the patriarch via the
"getDrawingPatriarch" method may cause a NullPointerException, due to an unset,
unchecked rawData value in AbstractEscherHolderRecord.
"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.
