Fixes #10931

In Java 8 and Java 11 runtimes, AWS Lambda runtime is packaged under lambdainternal package (it is com.amazonaws.services.lambda.runtime.api.client for new runtime likes Java 17 and Java 21)

I have

  • zipped /var/runtime/ folder in the AWS Lambda environment for Java 8 and Java 11 runtimes,
  • uploaded it to S3,
  • downloaded it to my local
  • and then unzipped

Then I have decompiled classes from LambdaSandboxJava-byol.jar and LambdaJavaRTEntry-byol.jar.

And as you can see below, AWS Lambda runtime internal classes are packaged under lambdainternal package and the internal handler (lambdainternal.EventHandlerLoader) we need to ignore is there.
