Description

Today this code produces an error:
class MyList extends ArrayList {

public MyList() {}
}

def x = [2, 3, 4] as MyList

This is because MyList does not have a constructor that takes a collection.

All collections have an addAll(Collection) method.
If the constructor fails then we should try the default constructor followed by a call to addAll.

I have the code fixed locally with test and can check in any time. Just want to get approval in case there is a backwards compatibility issue.
