Post File array using AngularJS and Jersey

Question

I am trying to post an array of files using ngFileUpload. ngFileUpload will transform the array into a FormData object using the following form:

inputName[$index] = [File Object]

Is there a way to use regex or ignore the [] in Jersey?

public String myResource(@FormDataParam("inputName") List<FormDataBodyPart> files) {
    // code
}

Or how can I remove the [] in angular before sending the request?
