Description

Not sure if this is a bug, but at least it is inconsistent.

According to the documentation, calling a closure with no arguments is equivalent to calling it with one argument of null. So this works as expected:

def f =

{a -> print(a)}

; f() // prints null

However,

def f =

{a, Object[] rest -> print(a)}; f()

fails with
groovy.lang.MissingMethodException: No signature of method: test$_run_closure1.call() is applicable for argument types: () values: {}

What's inconsistent is that

def f = {a, Object[] rest -> print(a)}

; f(null)

prints "null" just fine.
