Swing And JavaFX application run fails
I am trying to create a native-image of a straightforward application but it requires being a Swing application with JFrame and JFXPanel to run JavaFX UI as I am using Java Chromium Embedded Framework (JCEF) to replace Javafx WebView on Windows as GraalVM does not currently support it. And JavaFX does not render the browser correctly, hence Swing usage.
Plugin's build command runs perfectly fine but when I try to run the image using nativerun it fails to run.

Please let me know if any more information is needed
mvn gluonfx:runagent and click through everything before mvn gluonfx:build copy your .exe to graalvm\bin and execute it from there - if it works there, the awt and dependent dll's are missing and they must exist in the directory where you start the .exe
