[SOLVED] Issue loading .XML files with doc4J in Java

Issue loading .XML files with doc4J in Java

I am facing an issue where I cannot load even the sample word2003xml.xml which is provided by doc4J for tests in docx4j-samples-docx4j-8.3.1.zip found here https://www.docx4java.org/downloads.html

I tried loading the file using 2 different constructors but the result is the same.

WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(new FileInputStream(new File("C:\\Mine\\project4tests\\word2003xml.xml")));
WordprocessingMLPackage wordMLPackage2 = WordprocessingMLPackage.load(new java.io.File("C:\\Mine\\project4tests\\word2003xml.xml"));

Here is the exception that I am getting:

There is no issue loading a .DOCX file, however what I need to use the docx4J library is to convert an old .DOC (WordprocessingML more like an .XML) file into a .DOCX. Similar to what is done here https://coderanch.com/t/721499/java/Word-XML-DOCX

Does anybody know why I cannot load the file properly?
