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.

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?
