Curry method fails when using it in a chain with IllegalArgumentException

def c = { arg, Object[] extras -> arg + ', ' + extras.join(', ') }
def d = c.curry( 1 ) //curry first param only
assert d( 2, 3, 4 ) == '1, 2, 3, 4'
def e = c.curry( 1, 3 ) //curry part of Object[] also
assert e( 5 ) == '1, 3, 5'
def f = e.curry( 5, 7, 9, 11 ) //currying continues on Object
assert f( 13, 15 ) == '1, 3, 5, 7, 9, 11, 13, 15'

def a = { arg, Object[] extras -> arg + ', ' + extras.join(', ') }
//def b = a.curry( 1,2,3 ) //did not work
def c = a.curry( 1,[ 2,3 ] ) //works
def d = a.curry( 1,2 ) //works
//def e = d.curry( 3 ) //did not work
//def e = d.curry( [3] ) //did not work

java.lang.IllegalArgumentException: To curry 4 argument(s) expect index range 0..-4 but found 0
