Conflicting Kotlin versions for DynamoDB local `1.16.0`

As indicated in the post to another issue, we are facing conflicts when using the latest DynamoDB local version 1.16.0 in a Kotlin project. The reason is that the DynamoDB local jar seems to contain a copy of the Kotlin standard lib which conflicts with the one we are using for our project. We tested this both with a 1.4.x and 1.5.x version of Kotlin and both failed. Can you please fix the setup so that we can use Kotlin and DynamoDB local, again?

@zoewangg Thanks for the information about the release of 1.16.0. We were successfully able to start an embedded DynamoDB local instance in a JUnit test. However, once we now face some compiler warning:

w: Some JAR files in the classpath have the Kotlin Runtime library bundled into them. This may cause difficult to debug problems if there's a different version of the Kotlin Runtime library in the classpath. Consider removing these libraries from the classpath

Moreover, all integration tests fail due to conflicting Kotlin standard library files, see the following error details:

Action:
Correct the classpath of your application so that it contains a single, compatible version of kotlin.collections.MapsKt

Can you help us with the issue or guide us towrads a collegue that can provide more information?

We are using Kotlin 1.5, AWS SDK 2, Spring Boot, Corretto 11 as JRE, Gradle. Moreover, it seems like the DynamoDB local jar contains indeed a copy of the Kotlin standard library classes/files. Is it possible to remove those from the bundle?

I assume the Kotlin SDK is bundled to allow stand-alone running of the .jar? Why not create separate jars - one for inclusion as dependency, and uber-jar for stand-alone calls?

Bumping this. Still not working and this workaround is absurd. Please create a jar that is compatibile with Kotlin projects.
