I have a little Java app that retrieves a list of documents (XML response) using a digital signature PCKS#11. The webpage is paginated and after the first page the JAR crashes with no error or message. The JAR works perfectly on another PC with same windows, same JDK 17, same digital signature. The PC with the problem is a laptop with fresh Windows 10 Pro x64, Ryzen 5 7530U and 16GB of RAM so I doubt performance is an issue. Why can’t I see any message or error? I’ve tried every log, try/catch (Exception, Throwable). I have try/catch in main method where I start de WebSocket Server and still nothing no message…
