General

Hi, Not sure in which category to post. Feel free to delete if it’s not the right place

when I run the npl openapi --sourceDir api/src/main/npl-1.7, the end of the output looks like

NPL openapi has compilation warnings
Generating openapi for [project name]
Exception in thread "main" org.graalvm.nativeimage.MissingReflectionRegistrationError: The program tried to reflectively access

   java.util.Arrays$ArrayList.getDeclaredFields()

without it being registered for runtime reflection. Add java.util.Arrays$ArrayList.getDeclaredFields() to the reflection metadata to solve this problem. See https://www.graalvm.org/latest/reference-manual/native-image/metadata/#reflection for help.
