Description

the following script fails

def mymethod(Map kwargs=[:], arg1, arg2, Object[] args) {
    println "arg1: $arg1, arg2: $arg2, args: $args, kwargs: $kwargs"
}

mymethod('hello', 'world')
mymethod('hello', 'world', 'from', 'list')
mymethod('hello', 'world', 'from', 'list', from: 'kwargs')
mymethod('hello', 'world', from: 'kwargs')

the reason is that the optional map will cause the generation of two methods mymethod and each of these has a vargs argument. Groovy then somehow deselects both of them instead of choosing the most specific method. Code as this might be rarely used, but it should work
