@hanmaoren Unfortunately, it is still not clear what the problem is and how to reproduce it. I have checked the conversion of the attached document on my side and PDF document is produced properly.
Could you please clarify whether exception is thrown on your side, when you perform conversion or the resulting PDF is generated improperly.

Dear Alexey,
which part need to be clear? in our side, we use openjdk or oracle jdk run the code,it is work normal, but if change to ibm jdk is just coredump.

@hanmaoren Could you please provide stack trace of the exception thrown on your side? Also, please specify what version of Aspose.Words you use.

Thank you for providing additional information. We will continue to investigate this issue and let you know via this forum thread.


Unfortunately, we were unable to reproduce this issue on our side. Converting the attached RTF document to PDF works fine both using oracle jdk and ibm jdk. Please check the functionality using the latest version of the Aspose.Words library (currently it is 22.5).

We use the Aspose.Words library version of 22.3 & 22.4, later we will try with 22.5. thanks!

Dear Alex,

We tried to do the same conversion using ibm jdk on a linux environment using 22.5 and still got the error, see screenshot for the error.
Is the way I run it different from yours?
