Bug ID: 59058
Summary: OOM when opening OPCPackage with File but not with
InputStream (TIKA-1866)
Product: POI
Version: unspecified
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: OPC
Assignee: [email protected]
Reporter: [email protected]
Shawn Johnson recently posted a smallish docx file on TIKA-1866 that causes an
OOM.
WARNING: trying to parse this file in Intellij caused a system crash and
required a hard reboot on Windows.
I can reproduce this in pure POI with the following:
OPCPackage pkg = OPCPackage.open(path)
System.out.println("before creating extractor");
POIXMLTextExtractor poiExtractor =
ExtractorFactory.createExtractor(pkg);
System.out.println("finished creating extractor");
The OOM happens during createExtractor, and I never hit the second println.
However, there is no OOM with:
OPCPackage pkg = OPCPackage.open(Files.newInputStream(path));
System.out.println("before creating extractor");
POIXMLTextExtractor poiExtractor =
ExtractorFactory.createExtractor(pkg);
System.out.println("finished creating extractor");
Any idea what might cause the different treatment?
Java 1.8.0_72 on Windows.
