Description

When an operation definition consumes an application/json without specific parameter,
the Ada skeleton that is generated does not compile.

The Ada skeleton is missing a use Swagger.Streams statement so it can be fixed by hand.

The Ada generated code also produces several compilation warnings that we can fix.

openapi-generator version

5.0 and 5.1
