[java][jaxrs] codegen fails on nested lists trys to put generic in class name

[cenkentimist]

Description

output code for list of list of double includes invalid java List<Double>.class
Note that a list of doubles is generated correctly but a list of list of doubles is not.

Swagger-codegen version

2.2.2

Swagger declaration file content or url

swagger: '2.0'

info:
  title: example
  version: "0"

paths:
  /go:
    get:
      responses:
        200:
          description: "success"
          schema:
            type: array
            items: 
              type: array
              items:
                type: number
                format: double

this outputs invalid java to src/gen/java/io/swagger/api/GoApi.java

Command line used for generation

swagger-codegen generate --lang jaxrs --library jersey2 -i nowork.yaml

Steps to reproduce

create a file called nowork.yaml with the text given.
run the command swagger-codegen generate --lang jaxrs --library jersey2 -i nowork.yaml from the directory containing nowork.yaml
observe the generated file src/gen/java/io/swagger/api/GoApi.java it contains the bad java code List<Double>.class

@cenkentimist thanks for reporting the issue. Can you please also try generating a Java API client to see if it has the same issue? If no, we can plot the fix from Java client to JAX-RS server generator.

@wing328
swagger-codegen generate --lang jaxrs -i nowork.yaml --output box contains the issue
swagger-codegen generate --lang jaxrs-resteasy -i nowork.yaml --output box contains the issue
swagger-codegen generate --lang jaxrs-resteasy-eap -i nowork.yaml --output box contains the issue
swagger-codegen generate --lang jaxrs-spec -i nowork.yaml --output box contains the issue
swagger-codegen generate --lang jaxrs-cxf-cdi -i nowork.yaml --output box contains the issue
swagger-codegen generate --lang jaxrs-cxf-client -i nowork.yaml --output box generates

    @GET
    @Path("/go")
    @ApiOperation(value = "", tags={  })
    public List<List<List<Double>>> goGet();

in src/gen/java/io/swagger/api/DefaultApi.java which seems wrong though I can't confirm this.

swagger-codegen generate --lang java -i nowork.yaml --output box does NOT seem to have the problem
swagger-codegen generate --lang jaxrs-cxf -i nowork.yaml --output box does NOT seem to have the problem

By the way you guys have way too many java modes it's very confusing.
