Problem with PDF formatting (several instances of application)

We faced a problem with using ASPOSE Java library.
We using it as converter DOCX files to PDF. When we deploy several instances our web application in the same application server then sometimes the formatting of result PDF is broken. After redeploying it works well.
In case of one instance it also works well. The source docx file is the same for all servers.
Aspose library: aspose-words 16.5.0 (paid license)
Application server: Webshpere Liberty Profile 18.0.0.1
Java version: IBM JDK 1.8.0.5.21
JEE 7 application
OS: Linux

Do you use Native Library in your library? Can it be a result some kind of bug which is related to JNI or something like that?

@SergSW,

Please ZIP and attach your simplified input Word document and Aspose.Words generated PDF file showing the undesired behavior here for testing. We will then investigate the issue on our end and provide you more information.

Found a solution. The root cause is WLP 18.0.0.1 rollback to 17.x fixed the problem.
