Hmmm ... The de.codecentric.boot.admin.client.ClientServletApplicationTest hangs forever (in my fork build) ... Is this normal?

Locally its "working" ...

I found a major problem ... may you guys have an idea ...

Currently de.codecentric.boot.admin.client.config.SpringBootAdminClientRegistrationClientAutoConfigurationTest is failing for some of the defined "what kind of RegistrationClient is used" tests ... because de.codecentric.boot.admin.client.config.SpringBootAdminClientAutoConfiguration is mixing restclient and webclient and the bean-conditions which working with sb 3.5.x are no longer working because of the new splitting of the springboot dependencies ... may I'm wrong ...

I update the fork to M3 ... now some more new "incompatibilities" present ... all about jackson.

For example in de.codecentric.boot.admin.server.utils.jackson.EndpointMixinTest

The new org.springframework.boot.test.json.JacksonTester.initFields(Object, JsonMapper)

accept only tools.jackson.databind.json.JsonMapper from jackson-databind-3.0.0-rc9.

I can't find anything in spring's migration guide for this changes :-(

          wip: first version which compiles and no checkstyle warnings

c7ce798

- I did "mvn install -DskipTests=true -nsu -Dcheckstyle.skip=false -pl '!spring-boot-admin-docs'"
- spring-boot-admin-docs doesn't build successfully no glue why


          fix: add .checkstyle from eclipse to .gitignore

          wip: restclient vs. webclient

3c287b1

- wee need both starters because of import of RestTemplateAutoConfiguration,
  RestClientAutoConfiguration and WebClientAutoConfiguration in SpringBootAdminClientAutoConfiguration
- locally (win 11, gitbash, eclipse) ClientServletApplicationTest not working,
  the --spring.jackson.property-naming-strategy=SNAKE_CASE is not used (no glue why)
  - in github build its working - why is this?
- locally SpringBootAdminClientRegistrationClientAutoConfigurationTest is also not
  working 100% - a lot of "wrong" RegistrationClient are created, doesn't matter
  which "builders" are in the spring context
  - in github build its working - why is this?
