Jackson afterburner module is not compatible with Java11 and GraalVM native image

Not sure i'm missing something or not but Jackson AfterBurner module is not compatible with java11 and throwing following error when it is compiled with graalvm-21.01 native image

```

but when the afterburner module is removed it is working fine !

might be good idea to migrate to https://github.com/stevenschlansker/jackson-blackbird which is promising with Java11

Find the code at https://github.com/mokmnovatti/my-service

Start with the initialization path in aws-serverless-java-container-core/src/main/java/com/amazonaws/serverless/proxy/internal/LambdaContainerHandler.java around line 88, then trace the Afterburner calls shown through MyClassLoader.loadAndResolve. Reproduce the failure with the linked my-service project under Java 11 and GraalVM native image; done means the handler initializes without the reported UnsupportedFeatureError while preserving normal Jackson behavior.
