Description

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:
