Fix this comment, the line below does not set an error.

[kihong, 2014/05/14 03:44:25]

Done.

+    internals.setGeolocationPosition(document, ++mockLatitude, ++mockLongitude, ++mockAccuracy);
+    // The maximumAge is non-zero, so we expect the cached position, not the error from the service.
+    navigator.geolocation.getCurrentPosition(function(p) {

Actually, this is strange... maximum-age-expected.txt indicates that this test
gets no error. What's going on here?

As you mentioned, this is slightly strange there might be a timing issue for
checking error, but after adding testOverSignedIntMaximumAge() there is no
timing issue for adding error, So I changed test case properly.

     internals.setGeolocationPositionUnavailableError(document, mockMessage);
     // The maximumAge is non-zero, so we expect the cached position, not the error from the service.
     navigator.geolocation.getCurrentPosition(function(p) {
         checkPosition(p);
         testZeroMaximumAgeError();
     }, function(e) {
         testFailed('Error callback invoked unexpectedly');
         finishJSTest();
-    }, {maximumAge: 1000});
+    }, {maximumAge: 2147483648});
 }
 
 function testZeroMaximumAgeError() {
     // The default maximumAge is zero, so we expect the error from the service.
     navigator.geolocation.getCurrentPosition(function(p) {
         testFailed('Success callback invoked unexpectedly');
         finishJSTest();
     }, function(e) {
         checkError(e);
         finishJSTest();
     });
 }
 
 window.jsTestIsAsync = true;
