Please use the facilities of the framework for debugging any lifecycle issues. I was surprised when I found out that people did not use `--debug` for example or enabled logging of application startup events.

If you prefer GUI, Intellij even has a Spring Debugger: https://www.jetbrains.com/help/idea/spring-debugger.html

I stopped using Spring Debugger because for some inexplicable reason enabling it makes breaking at the breakpoint take minutes instead of seconds. For quite a while I didn't realize this was the problem, as IntelliJ started having it turned on by default at some point.

Fair point, honestly. It could easily be a skill issue from not doing this particular type of thing all that often.
