Default mapping of java byte array

[lscorcia]

Hi, I got bounced here from CXF Jira so I apologize in advance if it's not the right place to open this issue.

Basic repro project is here: https://github.com/apache/cxf/tree/cxf-3.4.3/distribution/src/main/release/samples/jax_rs/description_openapi_v3_web . Apply the attached patch file to expose the issue:
repro.txt.

I have a CXF/JAX-RS service that uses OpenAPIFeature to publish an OpenAPIv3 descriptor. As it's basically a duplicate of a SOAP Web Service, it does not have any annotation placed on its data types.
I am having troubles with fields of type byte[]. They are being represented in the descriptor as follows (see property called binary):

"components" : {
  "schemas" : {
    "Item" : {
      "type" : "object",
      "properties" : {
         "name" : {
            "type" : "string"
         },
         "value" : {
            "type" : "string"
         },
         "binary" : {
           "type" : "array",
           "items" : {
             "type" : "string",
             "format" : "byte"
           }
         }
       }
     }
   }
}

The byte array is wrapped in another array, which codegen tools parse as List of byte[] .
The correct representation for the parameter would be:

"binary": {     
  "type": "string",     
  "format": "byte" 
} 

Now, I understand I can annotate the hell out of these objects, but since the API perimeter is huge, it would mean a lot of work for something that should probably be working out of the box.
