GraalVM and SWT - How to analyse

Question

Finally, I got my java app (plain java with SWT and some JNA calls) compiled with GraalVM

BUT: on startup I have an segmentation fault while clicking on a UI-Element...

Has somebody experience how to analyse such kind of errors. I am looking for an approach how to handle this. Is there a general issue with SWT maybe?

Answer 1

Got it, it was just a missing entry in the jni-config.json.

BUT STILL QUESTION: Is it correct, to get my native-image-agent collecting all required components I have to play tester and click through all menu-entries, do all user action that triggers the possible paths that needs to capture by the native-image-agent???
