This is not related to Live Reload functionality.
This happens without any Live Reload (Vaadin functionality).
It happens because of Spring Boot dev tools.
We have a ticket for this : https://github.com/vaadin/spring/issues/226
and I believe there is another duplicate.
it is a nice experience for small changes (label, width change, etc.). But if I add a new method, I get “java.lang.reflect.GenericSignatureFormatError: Signature Parse error: Expected Field Type Signature”
as far as I can see, TravaOpenJDK is using JDK 11. All our Vaadin apps are using JDK14 with new features. So unfortunately, for now, we cannot use this for development
