PDF Converter + Apache POI 3.12: NoClassDefFoundError: org/apache/poi/wp/usermodel/Paragraph

[benneq]

When trying to convert some docx to pdf, it throws NoClassDefFoundError: org/apache/poi/wp/usermodel/Paragraph. This happens, when Apache POI 3.12 is on the ClassPath. When using POI 3.11 it works as expected.

This is the code we use:

OutputStream out = ...;
XWPFDocument doc = new XWPFDocument(docxFile.getInputStream());
PdfOptions options = PdfOptions.create().fontEncoding("windows-1250");
PdfConverter.getInstance().convert(doc, out, options);

pom.xml:
