Parsing the following JSON input and sending the resulting object to the
console yields the expected results for a JSNI JSON.parse() but yields
incorrect timestamps using a JsInterop JSON.parse() (with correct results
for all other properties). I'm completely at a loss as to why. Any
suggestions?
Input:
{"Contract":"STK:USD:PBA@NYSE","action":"onHistoricalData","bar":"D","bars":[{"close":21.76,"high":21.84,"low":21.38,"open":21.41,"time":1451520000,"volume":3067},{"close":21.56,"high":21.63,"low":21.14,"open":21.37,"time":1451865600,"volume":2565},{"close":21.49,"high":21.57,"low":21.26,"open":21.5,"time":1451952000,"volume":2303}],"callback":4,"metadata":{"noData":false},"t":1482867635,"t0":1451763575,"ticker":"STK:USD:PBA@NYSE"}
JSNI JSON parser:
native static Object parse( String json ) /*-{ return $wnd.JSON.parse( json
); }-*/;
JsInterop JSON parser:
@JsType( isNative = true, namespace = GLOBAL, name = "JSON" )
abstract public class JSON {
native static public <T> T parse( String json );
}
@JsType( isNative = true, namespace = JsPackage.GLOBAL, name = "Object" )
public class Message {
public int callback; // HARD-CODED in conjunction with Service::CALLBACK
}
// json from WebSocket
Window.console.info( parse( json ) );
Message message = JSON.parse( json );
Window.console.debug( message );

I tested the code in Chrome, Edge, and Safari and each yielded the same
results. Any suggestion as to where things are going awry will be greatly
appreciated.
