I get this error when running my project as a Spring Boot App, my guess is that the solution might not be too complicated:
Log of the error:

I am aware that this does not do much yet, but I would like to run it and open http://localhost:8080 and see the result.
I have tried to look into the buildpath libraries as described in other threads like: disableRegistry() doesn't exist (org.apache.tomcat.util.modeler.Registry), but i would not want to mess with it too much as I am new to this, any help would be much appreciated, thanks!
