Hotswap errors with > 24.5.*

[urkl]

Hi, I am experiencing significant issues with hot swapping in the new release.
I am using JBR 21.05 and the latest HotSwap Agent 2.01.
Has anyone managed to get it working with version 24.5 of Vaadin?

Do you have some more information about what is happening here? Is there another Caused by following the provided stacktrace?

Has anyone managed to get it working with version 24.5 of Vaadin?

Many people, including me, use it daily. There are always edge cases though
