Looks good.
The codenarc failure seems to be an unnecessary import in the test 🤷🏼♂️

Can't T be ByteArrayInputStream since you know the type?

What Does This Do
Prevent calling
start-invocationandend-invocationon the aws lambda extension multiple times.The lambda event needs to be serialized to json and shared with the extension. This event was properly serialized for the second wrapping, but not for the first. This means that once the extra handler wrapping is ignored, only one
aws.lambdaspan is being created, but the lack of event json means we won't be able to create inferred spans or properly handle trace context.The solution for this second problem is to add a new json adapter to serialize these types.
Motivation
In the most recent version of the java tracing layer for aws lambda, the request handler is being wrapped at least twice.
This double wrapping is causing the tracer to make calls to
start-invocationandend-invocationmultiple times. Aaws.lambdaroot span is created in the extension for every call to these endpoints.Additional Notes
