Spring Cloud sleuth memory leak issue

I am facing issue with spring cloud sleuth as it is leaking memory as I have gone through the dumps of my applications:
What does 13.05mb (40.3%) of Java Static org.springframework.cloud.sleuth.instrument.async.SleuthContextListener.CACHE
Spring Cloud Version: Hoxton.SR8
Spring Boot Version: 2.3.3.RELEASE
Please find the heapdump report below:
https://heaphero.io/my-heap-report.jsp?p=YXJjaGl2ZWQvMjAyMS8wNS8yNS8tLWhlYXBkdW1wLTE2MjE5MjE0MzYyNTMuaHByb2YtNS00Ni0xLmpzb24=
pls find the code repo below, which I am using in my appplication, Also on first run there is no memory leakage issue but on successive runs it shows the memory leakage issue as mentioned in the heapdump report

You have a complete mix of versions. Why do you say that you're using Hoxton and Boot 2.3 if you're not using Hoxton, you're using Greenwich and Boot 2.1

Please upgrade to the latest version of Sleuth and Boot. Please replicate this issue by going to start.spring.io and generating a new, fresh project.
Update:
With the 2020.0.3 release I've changed one class that used to cache a bean factory in such a way that now it stores a hash of that class.

The problem was that the method was not public ...
big facepalm for me ':D

Lots of dependences went to point: Could not find class [org.neo4j.ogm.session.SessionFactory] and it cant be added to pom.xml cause cant be found

Its chat bot on telegram api. Wanted to add registration and users bd. Done all by some guide. Had no errors with import while writing. But in Run started getting lots of errors:
First was: Caused by: java.lang.IllegalArgumentException: Could not find class [org.springframework.data.mongodb.MongoDbFactory]
I added it.
Then: org.springframework.data.jdbc.repository.config.JdbcRepositoryConfigExtensio - it was also added.
Then: org.neo4j/neo4j-ogm was also added ... aaand thats how i got to point where nothing works cause there is [ main] o.s.boot.SpringApplication : Application run failed
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [Main]; nested exception is java.lang.IllegalArgumentException: Could not find class [org.neo4j.ogm.session.SessionFactory] - and there is no "SessionFactory" on Maven.
What should I add to have help?
My main is:
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.telegram.telegrambots.ApiContextInitializer;
#SpringBootApplication
#EnableScheduling
public class Main {
