I’m facing an annoying problem with logging. We’re using slf4j with a custom log4j binding. I have a feedback-service module and most of it is written in Kotlin. I’m calling methods in this service in a controller in a sibling module that is all in Java. It would seem that if an exception is generated in the FeedbackService or FeedbackDao implementations it does not get logged anywhere. Yet exceptions generated in the controller get logged just fine. Any idea what could be the cause of this problem?
