Problems with spring integration in 14.3.1

I migrated my app from Vaadin 14.1.28 to Vaadin 14.3.1

In my app I use Spring but not Spring Boot.

Everything worked ok in 14.1.28.

Now, with 14.13.1, showing first page the app seems to go into a loop and the page doesn’t appear; the java process takes 40% of my CPU and never stop.

Removing all @Autowired in my code I see the first page but going to the second page, where I’ve many other @Autowired, the problem is still there.

I didn’t change anything in my code, till now.

What’s wrong ?
