Spring Boot 2.5.6

Thanks for the report but it's not clear why you believe this to be a problem in Spring Boot. The class in the issue title is part of Spring Cloud and that's all the information that you've provided.

If you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.

This has worked for me

<properties>
        <java.version>11</java.version>
        <spring-cloud.version>2020.0.3</spring-cloud.version>
        <mapstruct.version>1.4.2.Final</mapstruct.version>
        <maven.version>3.5.1</maven.version>
        <lombok.version>1.18.22</lombok.version>
        <kafka.version>3.1.2</kafka.version>
    </properties>
