Hello Team,

I updated the BIRT OSGi runtime used in our application (deployed on WildFly 27, running on java 11) from version 4.8 to 4.10.
When I try to generate a report I get a java.lang.ClassNotFoundException: com.lowagie.text.FontFactory.

I also tried BIRT 4.12, but I get the same error:

I've seen that iText has been replaced with OpenPDF. Maybe this change is related to my problem.

Do you have an idea what may cause my problem or what I can do to investigate further?

Thanks in advance.

With the latest built of the 4.14 the openpdf version is updated to version 1.3.30.
So you can test the newest built if it is solved in your solution.

I will close the issue but if you should have further topics with that, we can reopen the issue.
