produces "*/*" is converted into Accept: *_/_*

Swagger-codegen version: 2.2.1 (swagger-codegen-maven-plugin)

My yml file contains something like:

      consumes:
        - application/json
      produces:
        - '*/*'

Generating the client code from it works. However, I noticed that the server was crashing when returning the response to the client. After digging for quite some time I realized (with wireshark) that the client was sending the following HTTP Header: "Accept: /"

What is that?

As a workaround I did as follows:

ApiClient apiClient = new ApiClient();
apiClient.addDefaultHeader("Accept", "*");

It's due to a security measure we put in to avoid code injection. I'll see what I can do to handle */* as an exception.
