The bug

1. start the app with mvn clean quarkus:dev

2. visit http://localhost:8080/user with your browser, it should work 😊

   

3. edit the code by commenting something harmless (like the println) in the GreetingResource.kt

   

4. visit http://localhost:8080/user again with your browser, it should crash 😕

   

5. Edit the JsonModule.kt with something harmless (like adding a new line), it should start 😮
