Cannot create an instance of com.amazonaws.auth.AWS4Signer

I'm trying to provide a basic example of SQS integration with my custom native runtime, but I'm stuck on the following error Cannot create an instance of com.amazonaws.auth.AWS4Signer.

Repro:

1. Install leiningen & run wget https://raw.githubusercontent.com/FieryCod/holy-lambda/master/resources/fnative && chmod +x fnative && sudo mv fnative /usr/local/bin
2. git clone git@github.com:FieryCod/holy-lambda.git
3. cd examples/sqs-example
4. make install-holy-lambda compile native-compile native-sqs-invoke

The result is the error message:

{
  "errorType": "java.lang.IllegalStateException",
  "errorMessage": "Cannot create an instance of com.amazonaws.auth.AWS4Signer"
}

Spent almost 4 hours trying to somehow make it work. Would highly appreciate any help and hints.

You may need to register com.amazonaws.auth.AWS4Signer for reflection. You can read more about reflection here. Additionally, take a look at the native-image-agent which can help you detect reflectively accessed elements automatically.
