Description

The following simple iterator:

class bug10 implements Iterator {
int i = 0

Object next()

{ i++ return [ i, i*10, i*100 ] as Integer[] }

boolean hasNext()

{ i < 5 }

void remove() { }

static public void main(String[] args) {
def b = new bug10()

b.each

{ println it }
}
}

throws a NullPointerException in Closure.callViaReflection(). Oddly, calling a closure directly with an Object[] works just fine, e.g.:

c = { println it }

x = [3, 4, 5] as Object[]
c
