我在将docx 4j文档保存到OutputStream时遇到了一个问题，我不确定应该如何调试它。
我使用的是8.3.8版本的docx 4j-ImportXHTML和docx 4j版本的java 8。
一般来说，我会将一个html文档解析为docx 4j，并将其保存到OutputStream中，即

WordprocessingMLPackage docx = WordprocessingMLPackage.createPackage();
DocumentPart docPart = docx.getMainDocumentPart();
docPart.getContent().addAll(new XHTMLImporterImpl(docx).convert(htmlString, null));
docx.save(myOutputStream);.

不总是，这个进程崩溃，而其他一些它工作正常。所以我不能总是重现它。
我已经注销了org.docx4j.openpackaging，因为似乎有这个错误，但我不知道如何修复它。日志给予了以下结果：

在docx.save（myOutputStream）上调试时;它向我展示了一个例外：

org.docx4j.openpackaging.exceptions.Docx4JException: Problem saving part /word/document.xml
Failed to add parts from relationships of /

我不知道该如何解决这个问题。
先谢谢你
