Command line used for generation

java -jar swagger-codegen-cli-3.0.0-20180717.153005-90.jar generate -DhideGenerationTimestamp=true -l spring -i openapi.yaml

Actual generated code (shortened)

public interface RandomPetApi {
        @Authorization(value = "ApiKeyAuth")@Authorization(value = "AuthorizationProvider")
    }, tags={  })
    ResponseEntity<Pet> randomPetGet();
}

Expected generated code (shortened)

public interface RandomPetApi {
        @Authorization(value = "ApiKeyAuth"),  // This comma is missing in the generated code
        @Authorization(value = "AuthorizationProvider")
    }, tags={  })
    ResponseEntity<Pet> randomPetGet();
}

Start by running the reported swagger-codegen CLI command with the provided openapi.yaml, then trace the Spring server generation path that produces RandomPetApi and its authorization annotations. Done means the generated Java interface contains valid comma-separated annotations and no longer has the reported syntax error.
