Spring Boot - How to configure JMX default-domain

I saw several questions like this, but I am not quite sure to run Spring Boot properly in terms of JMX. Here my error at the console:

2020-07-24 09:54:10.243 ERROR 14272 --- [  restartedMain] o.s.boot.SpringApplication               : Application run failed

I have tried on deleting Tomcat and restarting, yet it gets the same error. Any factible solution for this scenery, please?

Solution

There was a conflict between versions in Intellij IDEA, from 2020.1.2 to 2020.1.4. So I decided to update the latest version and it gets the JMX properly fixed. @Stephane Nicoll thanks so much for your patience and my apologies with the inconveniece during this day. Best regards from Spain to Belgium.
