jaxrs codegen generates unused imports

Description

jaxrs codegen generates the following unused imports in my ApiService class:
import package.generated.api.;
import package.generated.data.*;
import package.generated.data.GeneratedModeal;
import package.generated.api.NotFoundException;
import org.glassfish.jersey.media.multipart.FormDataContentDisposition;
import java.util.List;
import java.io.InputStream;
Really annoying is the dependency to FormDataContentDisposition with forces me to add an unused dependency to my project.

Swagger-codegen version

2.2.0

Command line used for generation

java -Dmodels -Dapis -DapiTests=false -jar swagger-codegen-cli-2.2.0.jar generate -i xxx.yaml -l jaxrs -c config.json

Config

{
"sourceFolder" : "src/main/java",
"implFolder" : "src/main/java",
"modelPackage" : "package.generated.data",
"apiPackage" : "package.generated.api",
"invokerPackage" : "package.invoker",
"library" : "jersey2"
}

Start by reproducing the JAX-RS generation with swagger-codegen-cli 2.2.0, the supplied command, config, and a matching Swagger definition. Inspect the JAX-RS Jersey2 generation entry point and compare the generated ApiService imports; done means unused imports, especially FormDataContentDisposition and the listed package imports, are no longer emitted.
