NPE `Cannot read the array length because "<local2>" is null` with spring-petclinic

Commencez par AppMapConfig.java au niveau de isShallow(), puis examinez l’exemple appmap.yml avec une valeur packages vide et l’appel depuis Recorder.add(). Reproduisez l’échec de spring-petclinic via le plugin JetBrains et l’intégration Maven de l’IDE ; le travail est terminé lorsque les tests n’échouent plus avec la NullPointerException signalée.

• Java agent: 1.17.2 (local dev setup)
• Executed with the AppMap JetBrains plugin
• Using Maven integration with the IDE (and the plugin)
• Project: https://github.com/spring-projects/spring-petclinic

The following exception is reported in the log. The tests failed to run.
My assumption is that it's caused by an empty list of packages in appmap.yml. Such file was created by the IDE because the Maven project was not fully loaded/refreshed.

name: spring-petclinic
packages:
