Expected behavior The behaviour should be the same as when running in JVM and attach the extra handlers to the Logger that belongs to a category.

To Reproduce Steps to reproduce the behavior:

1. Configure named handlers and link to category
2. Build native image
3. During initialisation the exception occurs

Configuration

quarkus.log.handler.console."STRUCTURED_LOGGING".format=%m%n

quarkus.log.category."com.xyz.DocumentEventLogger".level=DEBUG
quarkus.log.category."com.xyz.DocumentEventLogger".handlers=STRUCTURED_LOGGING
