Vaadin 24.4.alpha25 project gets stuck in an infinite reload loop with VS Code

[marcushellberg]

Description of the bug

When starting a new Vaadin 24.4.alpha25 application in VS Code, it gets stuck in an infinite reload cycle caused by:

Change set: [/Users/mhellber/Desktop/my-app/target/classes [/Users/mhellber/Desktop/my-app/target/classes/META-INF/resources/images/empty-plant.png (MODIFY), /Users/mhellber/Desktop/my-app/target/classes/META-INF/resources/icons/icon.png (MODIFY), /Users/mhellber/Desktop/my-app/target/classes/banner.txt (MODIFY)]]

Running VS Code extension bisect, I could identify the extension causing the issue as the RedHat Java plugin.

Expected behavior

The application should start normally.

Minimal reproducible example

An application downloaded with https://start.vaadin.com/dl?preset=react&preset=partial-prerelease using alpha25.
Starting the app with VS Code running (either by running Application.java or with mvn) causes the app to reload constantly.

I couldn't reproduce it.
Tried running the app by running Application.java and mvn.
Also tried disable/enabled the extension, works without restarts.

I cannot reproduce this either, with the same setup, except that my operating system is ventura 13.1 i7
