Description

See http://groovy.markmail.org/message/wuskviqggfgzos7r?q=1%2E8+incompatibility&page=1

I have methods that support named parameters via a Map and positional method with the same name. Works on 1.7.x but gives stack overflow error on 1.8.

foo('xxxx')

def foo(final Map map) {
    println map
}

def foo(final name) {
    return foo(name: name)
}
