Summary: NegativeArraySizeException parsing xls file containing
OLE objects
Product: POI
Version: 3.0
Platform: Other
OS/Version: other
Status: NEW
Severity: blocker
Priority: P2
Component: HSSF
AssignedTo: dev@poi.apache.org
ReportedBy: trejkaz@trypticon.org
I crafted a test Excel document in Excel 2003, putting embedded Word and
PowerPoint objects inside it.
I didn't expect it to handle these, but what it did was much worse than my
expectations. :-)
Test code and file will be attached in a minute, results in the following exception.
java.lang.NegativeArraySizeException

Proposed fix
Code in EscherBlipRecord.getRecordSize() was saying that the length of the
record was the length of the blip data plus 4, but the header size is actually
8.
Fixed by using the actual HEADER_SIZE constant. File now at least parses as
expected.
