I am following this blog to try out a Spring-Boot-Admin application. And when I run the app it fails with the below error:
Application run failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'adminHandlerMapping' defined in class path resource [de/codecentric/boot/admin/server/config/AdminServerWebConfiguration$ServletRestApiConfirguation.class]:
Invocation of init method failed; nested exception is java.lang.StackOverflowError
I look further below and find these below lines:

Not sure if there is some circular dependency in the jars. Any idea please?
The comment by @the hand of NOD made me relook into my pom.xml file and the pom.xml file provided in the blog
The problem lies in the version number of the spring-boot-starter-parent. The tutorial uses a version 2.1.0.RELEASE whereas the latest one when you prepare a project from Spring Intializr is 2.2.1.RELEASE
I downgraded to 2.1.0.RELEASE and it worked! With 2.2.1.RELEASE there is some dependency that is going cyclic with spring-boot-admin-starter-server
P.S. It seems that the codecentric team is already working upon it and would release the 2.2.0 compliant version by 22 Nov 2019 (https://github.com/codecentric/spring-boot-admin/milestones)
