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

從 aws-serverless-java-container-core/src/main/java/com/amazonaws/serverless/proxy/internal/LambdaContainerHandler.java 第 88 行附近的初始化路徑開始，然後追蹤顯示的 Afterburner 呼叫，直到 MyClassLoader.loadAndResolve。在 Java 11 和 GraalVM native image 下使用連結的 my-service 專案重現此失敗；完成條件是 handler 能夠初始化且不會出現回報的 UnsupportedFeatureError，同時保留正常的 Jackson 行為。
