Línea de trabajo

Comienza con AppMapConfig.java en isShallow(), luego inspecciona el ejemplo de appmap.yml con un valor vacío para packages y la llamada desde Recorder.add(). Reproduce el fallo de spring-petclinic mediante el plugin de JetBrains y la integración de Maven con el IDE; se considera terminado cuando las pruebas ya no fallen con la NullPointerException indicada.

Descripción

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:
