Svante Schubert commented on ODFTOOLKIT-402:
--------------------------------------------
Could you take a another look into the validator? The same problem still occurs
in the validator, I have added a test validateEncryptedODT() to the project.
If we only use ZipFile in opposite to ZipInputStream is there still a way of
in-memory storing of the document?
As the mimetype is the first file in the ZIP without compression, there is no
"data-descriptor" allowed. Could we avoid this descriptor somehow?

> Project: ODF Toolkit
> Issue Type: Bug
> Components: odfdom

>
> Any encrypted ODF file written by LibreOffice reproducibly fails to open:
> Document document = Document.loadDocument(new File(args[0]), "abc");
> due to an exception produced early in parsing the ZIP file. The exception is
> masked by the NullPointerException in the exception handler as per
> ODFTOOLKIT-401, but if that is patched, the original exception is this:
> java.util.zip.ZipException: only DEFLATED entries can have EXT descriptor
> at java.util.zip.ZipInputStream.readLOC(ZipInputStream.java:309)
> at java.util.zip.ZipInputStream.getNextEntry(ZipInputStream.java:121)
