quarkus-amazon-lambda-rest doesn't support Java 17 ?

[nicolasduminil]

Describe the bug

I'm using Quarkus 3.7.4 with the quarkus-amazon-lambda-rest extension. The build generates the following sam.jvm.yaml file in the target directory:

  AWSTemplateFormatVersion: '2010-09-09'
  Transform: AWS::Serverless-2016-10-31
  Description: AWS Serverless Quarkus HTTP - rest-gateway-api
  Globals:
    Api:
      EndpointConfiguration: REGIONAL
      BinaryMediaTypes:
        - "*/*"

  Resources:
    RestGatewayApi:
      Type: AWS::Serverless::Function
      Properties:
        Handler: io.quarkus.amazon.lambda.runtime.QuarkusStreamHandler::handleRequest
        Runtime: java11
        CodeUri: function.zip
        MemorySize: 512
        Policies: AWSLambdaBasicExecutionRole
        Timeout: 15
        Events:
          GetResource:
            Type: Api
            Properties:
              Path: /{proxy+}
              Method: any

  Outputs:
    RestGatewayApiApi:
      Description: URL for application
      Value: !Sub 'https://${ServerlessRestApi}.execute-api.${AWS::Region}.amazonaws.com/Prod/'
      Export:
        Name: RestGatewayApiApi

The default runtime is, for some reason, Java 11. I'm modifying it to be Java 17 and I run the floowing command:

sam local start-api -t target/sam.jvm.yaml

Then running my integration tests I get the following:

Mounting RestGatewayApi at http://127.0.0.1:3000/{proxy+} [DELETE, GET, HEAD, OPTIONS, PATCH, POST, PUT]
You can now browse to the above endpoints to invoke your functions. You do not need to restart/reload SAM CLI while working on your functions, changes will be reflected instantly/automatically. If you used sam build before running local commands, you will need to re-run sam build for the changes to be picked up. You only need to restart SAM CLI if you update your AWS SAM template

Expected behavior

I expect that the integration tests run successfully.

Actual behavior

The mention exception is raised.

raises exactly the same exception.

We should definitely adjust the default runtime but we need to find a working value.

From what I can see, java17 should work: https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html

The descriptor might need some other changes but I have no experience with lambdas so can't really help.

[nicolasduminil]

The file sam.jvm.yaml is quite simple an, besides the Runtime property, that I adjusted, there is nothing else to be modified. It defines the handler class, the functions.zip URI, memory size, security roles, timeouts, etc. None of these cannot impact the supported Java version.
What seems to happen is that the content of functions.zip is compiled with Java 11 insted of Java 17 and this is done by the quarkus-amazon-lambda-rest extension. Are there any properties that can be used to configure the Java version ?

[nicolasduminil]

Using the last release of SAM CLI (1.110.0) fixes the issue.
