    - name: "identifier"
      in: "path"

      format: "int64"

Generates partial PathApiService.java

public abstract class PathApiService {
    
    public abstract Response pathIdentifierGet(Integer identifier,SecurityContext securityContext) throws NotFoundException;

where identifier should be Long.

Command line used for generation

swagger-codegen-cli-3.0.0-20180411.134218-60.jar generate -l jaxrs-jersey -i pathLongBug.yaml -o pathLongBug

Steps to reproduce

Copy paste example pathLongBug.yaml file
Run command line above
Go to pathLongBug\src\gen\java\io\swagger\api. identifier should be a Long.

Suggest a fix/enhancement

The format property should be respected for path operation parameter types.

Note this is different from issue 7754

Start by saving the supplied Swagger declaration as pathLongBug.yaml and running the documented swagger-codegen-cli command with the jaxrs-jersey generator. Inspect the generated PathApiService.java and compare the type of identifier with the declared integer format int64. Done means the generated pathIdentifierGet method uses Long for identifier.
