Reproduce ClassCastException during file upload:

Execute codegen.sh and have a look at the wrong cast to class File in app/src/main/java/test/fileupload/PetApiVerticle.java. This refers to the (fixed?) bug in phiz71/vertx-swagger#93

Reproduce the vertx NPE during fileUpload

Minimal setup to reproduce a failing file upload in vertx

• Run gradle task run to deploy the verticle
• Execute ./upload.sh

--> NPE thrown in BodyHandlerImpl (@ context.vertx().fileSystem() since context.vertx() returns null)
