Description

Referenced jar:
-odfdom-java-0.8.10-incubation-SNAPSHOT-jar-with-dependencies.jar
-simple-odf-0.8.1-incubation-SNAPSHOT-jar-with-dependencies.jar

Steps:
1. Save a .ods file with password manually
2. Execute API "SpreadsheetDocument.load(filePath, password)", it throws NullPointerException.

Reason:
1. In org.odftoolkit.odfdom.pkg.ZipHelper.line87, "System.getProperty("Java.version")" returns null, then it cause NPE. Obviously, the parameter here should use "java.version" instead.
2. The key point is line83, "inputStream.getNextEntry()" throws java.util.zip.ZipException: only DEFLATED entries can have EXT descriptor.

Remark:
If use API Document.save(File file, String password) to save a new ods file with password, then invoke Document.loadDocument(File file, String password), it works.
