'hasMore' doesn't work as expected.

Description

I want to use 'swagger-codegen-maven-plugin' to generate Java code with custom template.
But it doesn't work as I expected.

Swagger-codegen version

2.4.7 and lower

Swagger declaration file content or url

 produces:
 - "application/xml"
 - "application/json"

I expect:

@Produces({"application/xml","application/json"})

but got:

@Produces({"@Produces({"application/xml","application/json"})

and mustache template is:

{{#produces}}@Produces({"{{/produces}}{{#produces}}{{#mediaType}}{{mediaType}}{{/mediaType}}{{#hasMore}}","{{/hasMore}}{{^hasMore}}"}){{/hasMore}}{{/produces}}

I'm not sure whether it's a bug.

Start with the supplied swagger-codegen-maven-plugin configuration, Swagger declaration, and Mustache template, then reproduce the generated Java output for swagger-codegen 2.4.7 or lower. Compare the handling of hasMore with the expected @Produces annotation and determine what output marks the issue as fixed; no test or source file is named in the report.
