Jar file crashes due to PDF output button?

Question

Java

After launching the jar file and passing the authorization window, the jar crashes. At random, it was revealed that everything breaks due to two lines of the button for creating a PDF file. In my form, the salary is calculated and the variables are output to the jar file. Inside the development environment, the form works perfectly, but something goes wrong in the jar file. For pdf I use itextpdf library. I think it's all about my pom.... Can you tell me what the problem is ( Here is my pom:

Good afternoon.
Run your jar via cli (bash, commander, powershell, etc.). Then try the appropriate operation to get the desired exception. This exception will be displayed in the console. It remains only to find the cause and fix it.
