[JENKINS-68154] Custom headers with special characters in their names

According to the documentation of the plugin, you can define custom headers for requests with a syntax like this one:

def response = httpRequest customHeaders: [[name: 'foo', value: 'bar']]

The problem arises when you try to use custom headers that use names with non-standard characters. I can't see the way to do something like this:

def response = httpRequest customHeaders: [["my-custom-header-with-hyphen-separator": "${varName}"]]

I know I can do it the hard way:

def headers = new ArrayList()


def headerName1 = 'my-custom-header-with-hyphen-separator'

def varName1 = 'abc'

headers.add(new jenkins.plugins.http_request.util.HttpRequestNameValuePair("${headerName1}","${varName1}"))

However I don't think that's the preferred method as it involves granting certain permissions to scripts.

Under normal circumstances, I would've expected here to use this kind of syntax:

def headers = [ "${headerName1}":"${varName1}","${headerName2}": "${varName2}" ]

Pretty much a json object with one or more key/value pairs.

So, is this possible? is there any alternative syntax that can be used right now to avoid working directly with Java classes?
