Seems like it might be the same as vaadin/flow#19280

I am experiencing the same issue. If I download the Hello World project FLOW/Java, it starts fine. But if I use the app starter UI (https://start.vaadin.com/app/p) and create a React (Hilla) app, I get an infinite restart loop.

I see this in the output:
"Restarting due to 2 class path changes (0 additions, 0 deletions, 2 modifications)"

I feel like the React build is creating files that the Spring devtools is seeing as new. Perhaps there is a way to exclude those files? I tried to identify and ignore a couple of files that I thought might be the culprits, but no luck so far.

I should note that adding the following to application.properties prevents the infinite restarts. However, it at least partly disabled hot reloading as well:

spring.devtools.restart.enabled = false

I found a way to stop the application from rebooting.
Until a permanent solution comes from the Vaadin team or the IDE maintainers, it seems like the hot-reload scripts are targeting files in src/main/frontend/generated/.
This causes the application to keep rebooting/reloading infinitely.

For me, the solution was to add an exclude watch for that directory.
Updates to the backend and frontend hot reload now work as expected.

Apply this in your VSCode/Cursor settings, add the following to your settings.json:

{
  "files.watcherExclude": {
    "**/src/main/frontend/generated/**": true
  },
}

Thank you Andy. I was also able to get around this issue, but my solution may not be as workable for everyone as yours. I disabled the Java Debugger VSCode extension from Microsoft. That stopped the continuous reloading behavior. When I re-enabled the plugin, it did not return. The problem is, I have no explanation for why that would have worked.
