Starting with version 3.8.1 (observed with 3.8.2 as well), the liquibase-core.jar contains files in META-INF/services that belong to Jackson. This leads to runtime errors when Liquibase and Jackson are used in the same project. I've built a minimal example project at https://github.com/MenschNestor/liquibase-bug that exposes the issue, which revolves around the ServiceLoader mechanism in Java.
Please make sure that the JAR file does not contain foreign service provider configuration files.
