When using the Jetty Maven plugin together with JRebel, ensure that automatic restart is disabled (omit or set `<scanIntervalSeconds>` to a value of `0` or less).

== Troubleshooting Startup Delays with JRebel
This step can be followed to reduce the startup time when using JRebel in debug mode in IntelliJ IDE.
Disable the Reactive Debugger:

- Navigate to File → Settings → Languages & Frameworks → Reactive Streams.
- Uncheck the Enable Reactor Debug mode checkbox.

== Current Limitations

Since the server doesn't restart, modifications to startup listeners and code that connects frontend and backend components, such as adding a new [classname]`LitTemplate` class, aren't reflected. However, modifications to routes are picked up.
