/**
 * NASHORN-111 :  ClassCastException from JSON.stringify

 */
// problem 1
// the conversions in TernaryNode are not necessary, but they should not cause problems. They did
// this was because the result of Global.allocate(Object[])Object which returns a NativeObject.
// was tracked as an object type on our stack. The type system did not recognize this as an array.
// Then the explicit conversions became "convert NativeArray->Object[]" which is a checkccast Object[]
// which naturally failed.

// I pushed the appropriate arraytype on the stack for Global.allocate.

// I also removed the conversions in CodeGen, all conversions should be done in Lower, as
// NASHORN-706 states.

var silent = false;
var stdio = silent ? ['pipe', 'pipe', 'pipe', 'ipc'] : [0, 1, 2, 'ipc'];

// This made the test pass, but it's still not correct to pick widest types for array
// and primitives. Widest(Object[], int) gave us Object[] which makes no sense. This is used
// by lower to type the conversions, so function b below also failed until I made a change
// ty type widest to actually return the widest common denominator, if both aren't arrays

function b() {
    var silent2 = false;
    var stdio2 = silent2 ? [1,2,3] : 17;
