---------------------------------------------------
Summary: NullPointerException caused by ZipException, loading file
generated by LibreOffice 3.6
Key: ODFTOOLKIT-353
URL: https://issues.apache.org/jira/browse/ODFTOOLKIT-353
Project: ODF Toolkit
Issue Type: Bug
Components: odfdom
Affects Versions: odfdom-0.8.7, odfdom-0.8.8
Environment: Oracle JDK 1.6.0_22 x64
Windows 7 Professional 64 bits
LibreOffice 3.6
Reporter: Jean-Baptiste Lièvremont
Attachments: empty.odt
I am trying to load the attached (?) empty ODT file generated with LibreOffice
3.6. I put the file on the classpath in order to be able to load it through
getResourceAsStream.
The NPE is as follows:
java.lang.NullPointerException
at org.odftoolkit.odfdom.pkg.ZipHelper.entriesToMap(ZipHelper.java:86)
at org.odftoolkit.odfdom.pkg.OdfPackage.readZip(OdfPackage.java:329)
at
org.odftoolkit.odfdom.pkg.OdfPackage.initializeZip(OdfPackage.java:324)

at
org.odftoolkit.odfdom.doc.OdfTextDocument.loadDocument(OdfTextDocument.java:150)
at (redacted)
Debugging into ZipHelper, I found that the NPE is caused by an erroneous access
to the "Java.version" system property (which shoud probably read "java.version"
- in lowercase).
Now, if I explicitly define Java.version (-DJava.version=1.6.0), I get the
following ZipException:
java.util.zip.ZipException: invalid entry CRC (expected 0xef5e424d but got
0x585c5715)

Of course, the file loads just fine in LibreOffice 3.6, as well as 7-Zip, but
e.g Word 2010 also says that it is corrupt.
So my guess is that the ZipException is somehow provoked by an issue with
LibreOffice 3.6 (but should not 7-Zip also complain in case of a bad CRC ?).
Anyhow, there is an unprotected read - and comparison - of an unexisting system
property.
