jackson-module-kotlin: java.lang.NoClassDefFoundError: kotlin/jvm/JvmInline

I hope to support both Java and kolitin in my project, but Jackson module kotlin is introduced into my POM. In the Java environment, this package will report errors

SBA request actuator/health threw classdefNotFoundException in jackson serializer. Had to downgrade kotlin version to 2.12.0. Bugfix thread: https://github.com/FasterXML/jackson-module-kotlin/issues/5... — committed to BitWeb/java-core-lib by deleted user 2 years ago

My guess is that it is due to a combination of Kotlin versions.

JvmInline is a class introduced in Kotlin 1.5. Since jackson-module-kotlin is Kotlin 1.5 since 2.13, I think that using 2.12 series will solve the problem.

I’ve encountered the same thing on upgrading from Spring Boot 2.4.x to 2.6.1.

Upgrading from kotlin version 1.4.0 to 1.6.0 fixed this for me weirdly. I’ve not had time to figure out why.
