The code bellow should produce one success alert (for first item) and three alerts for failed attempts (last three items). But it ain't so: it produces success alerts for the last two items.

I searched the web and json.org and I couldn't find logical explanation, so I am filling this as a bug.

var a = new Array();
a[0] = '{ "fridge": "beer" }';
a[1] = "pizza";
a[2] = "true";
a[3] = "1";

for (var i = 0; i < a.length; i++) {
	
	try {
		var b = jQuery.parseJSON(a[i]);
		alert("Parsing \\"" + a[i] + "\\" was success.");
	} catch(e) {
		alert("Parsing \\"" + a[i] + "\\" failed.");
	}
	
}
