Description

When I try to convert a primitive array to java.util.Set using the "as" operator, it looks like Groovy tries to create an instance of java.util.Set (as opposed to creating an instance of some class which implements java.util.Set).

demo.groovy
def intArray = [1, 2, 3] as int[]
def setOfInt = intArray as Set
println setOfInt

conversion_problem $ groovy -version
