Hello,

we have a simlilar Problem which occurs when just saving our doc. It appeared while performing a stress test with approx. 20 clients firing to our server (always the same document). We haven't had this error so far what makes me believe that it might be a threading issue? We are using Aspose.Words for Java 10.6.0.

Here's the stacktrace:

Hi Klemens,


Thanks for your inquiry.

There was a issue similar to this reported a while ago. It related to ExternalFontCache and a multithreaded environment. The issue was fixed in 11.1.0 (February release). Could you try using the latest version of Aspose.Words for Java (11.3.0) and test if the issue you are having issue is resolved by that the latest version?

Thanks,
