Description

Consider the following:

@Grab('org.apache.commons:commons-collections4:4.4')
import org.apache.commons.collections4.FluentIterable

def iterable = FluentIterable.of(['foo','bar','baz'])
def array = iterable as String[]
print array.length

This script prints "1". We are expecting an array of 3 strings.
