SpringBoot SpringBoot 2.5.0 - application failed to start when using Liquibase (ClassCastException)

Hi, After upgrading from 2.4.5 to 2.5.0, I get the following stack when application starts. I'm using latest Liquibase in my build.gradle : implementation 'org.liquibase:liquibase-core:4.3.5'

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'liquibase' defined in class path resource [org/springframework/boot/autoconfigure/liquibase/LiquibaseAutoConfiguration$LiquibaseConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [liquibase.integration.spring.SpringLiquibase]: Factory method 'liquibase' threw exception; nested exception is java.lang.ClassCastException: class com.zaxxer.hikari.HikariDataSource cannot be cast to class org.springframework.jdbc.datasource.SimpleDriverDataSource (com.zaxxer.hikari.HikariDataSource and org.springframework.jdbc.datasource.SimpleDriverDataSource are in unnamed module of loader 'app')

Thank you, Ori.

Thanks for the report @oridool. As you've mentioned, this is indeed a duplicate of #26644

Comment From: oridool

I can confirm that the workaround provided by @agebhar1 works for Liquibase as well:

spring:
  liquibase:
    url: ${spring.datasource.url}

@snicoll - is it going to be fixed, or it is a non-issue and this workaround is how it should have been working from start?

Thanks, Ori.
