Bad null argument handling

[EQuincerot]

If you do so:

def myMethod(String foo) {
  return 'bar'
}

myMethod null

Then you get : java.lang.IllegalArgumentException: wrong number of arguments.
We need a way to make the difference between a null value of an argument and its non-existence.

Hi,
I code a step:

def call(Map vars) {
...
}

When I call:

myStep(null)

Then I am still getting: java.lang.IllegalArgumentException: wrong number of arguments.
I've tested with versions 1.0 and 1.1.
I've tested with the same original sample of this issue, and the problem still happens.

@ozangunalp Can you check this for me? (please)
