Getting java.lang.NoClassDefFoundError: brave/internal/HexCodec after upgrading to Spring Boot 2.3.8.RELEASE

I am trying to upgrade my SpringBoot version from 2.0.x to 2.3.8.RELEASE. After the update, on refreshing the Spring Config Server, I am getting java.lang.NoClassDefFoundError: brave/internal/HexCodec in my application logs. My app is deployed over PCF and uses below dependencies in addition to company's internal dependency.

I assume I am getting this issue because of Zipkins being used in Spring Sleuth(We have this in our company's internal dependency). I tried setting spring.zepkin.enabled=false and I also tried to create the below bean with org.springframework.cloud:spring-cloud-starter-sleuth:2.2.8.RELEASE but still I got the same error.
#Bean
Reporter<Span> reporter() {
return Reporter.NOOP;
}
Application console error message: org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: brave/internal/HexCodec
At this point, I am not even sure if I am on right track or not. Please let me know if more information is required.

Could you please use the latest of that release train: Hoxton.SR11 and the latest Spring Boot 2.3.x?
With these you should see org.springframework.cloud:spring-cloud-starter-zipkin:2.2.8.RELEASE with the matching Sleuth dependencies. This should ensure that you are using the right version of Brave.
If this does not work, please check your dependency tree and the Spring Cloud BOM and ensure you are using the right versions.

The code works:
.from(Http.inboundGateway("goods/{operation}")
.requestMapping(m -> m.methods(HttpMethod.POST))
.requestPayloadType(String.class)
.headerExpression(MessageHeaderName.OPERATION, "#pathVariables.operation"))
//......
It still works when #EnableFeignClients add to Spring Boot Application entry.
But once the #FeignClient instance wired to(by #Autowired) any config Class(#Configuration), it's not working.
I have checked http://myproject/mappings (The request mappings info provided by Spring boot), mappings "/goods/**" disappeared.
It's a simple project that explains this problem: https://github.com/Princelo/demoForSiAndFeignProblem/blob/master/src/main/java/com/example/demo/config/AnyConfig.java

Please, see https://github.com/spring-projects/spring-integration/issues/2752 for more info and for tracking the fix.
Meanwhile as a workaround I suggest to have a #Lazy whenever you try to inject Feign client interfaces.
The problem that FeignClientFactoryBean initiate a new child ApplicationContext for each Feign cleint and calls a ContextRefreshedEvent for them too early. The IntegrationRequestMappingHandlerMapping doesn't check for the context of the event and marks itself initialized wrong way, missing the scan for appropriate HTTP components.

Why override org.webjars when using org.springframework.cloud dependency ? there is any dependency vise versa? I am confused .

issue with circuit breaker and AbstractCloudConfig when upgrading to spring boot 2.0.3

Currently we are upgrading our app to use spring boot 2.0.3.
The app is deployed to PCF and uses circuit breaker, also we use AbstractCloudConfig in our code in order to initialize a session and retrieve the properties for cassandra from the user provided service.
We noticed that when checking the health using actuator/health , rabbit fails and the cause is due to connection refused.
It's trying to connect to localhost instead of the host provided by the rabbit service in pcf.
After testing and debugging the app , we came to a conclusion that the issue is due to AbstractCloudConfig.
In order to verify this conclusion , we created a demo app that uses circuit breaker and also AbstractCloudConfig and we noticed the same issue, When we removed the use of AbstractCloudConfig everything was fine.
Is there a different way to use AbstractCloudConfig in spring boot 2.0.3 or this is an issue?

Is Spring-Boot (still) not working with JSR310Converters for Java 8 LocalDate by default?

I am using Java 8 along with Spring-Boot 1.5.10.RELEASE.
I still seem to need #EntityScan(basePackageClasses = { Application.class, Jsr310JpaConverters.class }) in my Application class.
I thought Spring-Boot supports Jsr310/Java8 LocalDate API starting 1.4 (according to https://github.com/spring-projects/spring-boot/issues/2721)? I am asking this, because in the 4th reply on that issue mentioned above it is mentioned, that using #EntityScan switches off the default behavior. I think
I should not need this - or do I?

In my effective POM I do have both hazelcast-hibernate4 and hazelcast-hibernate5. Is this correct? Or is something wrong with my pom.xml?
Related SO-Q&A: New Spring Data JDK8 Jsr310JpaConverters not working automatically?
Note: this question is not related to the jackson-part (JSON) of the JSR310 problem as I did solve it by properly declaring com.fasterxml.jackson.datatype:jackson-datatype-jsr310 as a dependency.
Update:
According to mvn depedency:tree I only use hibernate-core 5.0.12.Final, hibernate-entitymanager 5.0.12.Final and hibernate-validator 5.3.6.Final. All of them are parts of some spring-boot packages.
This leaves me puzzled: if JSR310Convverters for LocalDate were implemented in hibernate 5 - why do I still have to use #EntityScan-annotation?

You have to add dependency:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-java8</artifactId>
</dependency>
and you won't need to specify #EntityScan(basePackageClasses = {Application.class, Jsr310JpaConverters.class}) on your Application class anymore

I found an "okay"-solution for myself. There are 2 aspects to cover in this context:
JSON-conversion
JPA-conversion
For JSON-conversion I set this property in the application.properties file:
spring.jackson.serialization.WRITE_DATES_AS_TIMESTAMPS=false
In order to have the database (I am using H2) contain TIMESTAMP-type columns with values rather than VARBINARY-type columns with values one cannot read right away nor properly sort, one currently seems to have to include:
#EntityScan(basePackageClasses = { Application.class, Jsr310JpaConverters.class })
I wish it would automatically use those converters since I am on Java 8 anyway, but unfortunately it does not seem to do that.
Please note the following:
This isn't quite as straightforward as I thought. Using #EntityScan on
one of our configuration classes has the unwanted side-effect of
switching off the default which is retrieved from
AutoConfigurationPackages
