[Question] Want to understand on what basis is the Response body implementation picked

[arrajeev87]

When we fire a request using the feign client we get the body of the type "feign.Response$ByteArrayBody"
But the same API call with a different request give the response body of type "feign.okhttp.OkHttpClient$1"

So wanted to understand why is this different? On what basis is the implementation selected?

Depends on when the body is read. If it's inside the Client and has not been passed to a Decoder, you'll see the client's specific implementation. If it's passed to a Decoder or you have the log level for Feign set to Headers, the response will be read into memory into a ByteArray, changing the type.
