Bug ID: 63330
Summary: XSSFBParser should use skipfully
Product: POI
Version: 4.0.x-dev
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: XSSF
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
There were a handful of new exceptions on xlsb files on a recent run of
regression tests.
I'm not able to replicate this problem and the files I've reviewed are not
truncated. I _think_ the problem is that we're relying on "skip" rather than
"skipFully".
I propose modifying the one line in XSSFBParser and fixing
LittleEndianInputStream's "skipFully" to throw an EOF if the skip isn't
complete...to make it parallel with its "readFully"
The stacktraces were all triggered by running getAbsPathMetadata():
org.apache.poi.xssf.binary.XSSFBParseException: End of file reached before
expected.
Tried to skip 105, but only skipped 61
