NPE on org.springframework.boot.SpringApplication.getMainApplicationClass() with AOT

SpringDelegatingLambdaContainerHandler と示されている依存関係のバージョンを使用して、AOT Lambda の起動を再現します。SpringApplication.getMainApplicationClass() と EnvironmentPostProcessorApplicationListener.addAotGeneratedEnvironmentPostProcessorIfNecessary から開始し、その後 ServerlessMVC の初期化パスを追跡します。報告された NPE や後続の dispatcher 失敗が発生せずにアプリケーションが起動すれば完了です。

Hi!
I'm trying to implement AOT into a simple java lambda

I'm using the com.amazonaws.serverless.proxy.spring.SpringDelegatingLambdaContainerHandler handler

Dependencies:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <version>3.5.7</version>
</dependency>
<dependency>
    <groupId>com.amazonaws.serverless</groupId>
    <artifactId>aws-serverless-java-container-springboot3</artifactId>
    <version>2.1.5</version>
</dependency>

Logs:
