Have you also tried the latest version of Aspose.Words for Java i.e. 20.1 on your end? In case the problem still remains, please ZIP and upload your input RTF Word document and piece of source code here for testing. We will then investigate the issue on our end and provide you more information.

I tried version 20.1 and I still get the same error. Attached is one of the RTF files that throws the error. I also included the function I’m using to do the conversion. The exception happens at line 23 of this code.

It is a huge problem for us since it is happening with so many documents.

Thank you for taking a look.
