1239954 - xpcshell test timed out with SettingsSevice.createlock().get()

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: General, defect)

Description

[Thomas Nguyen (:tnguyen)]

I'm writing some xpcshell test cases running on emulator-kk and found that if the code contains SettingsSevice.createlock().get(), xpcshell test will be timed out, even all the tests are run as PASS.
Trying to run a simple test as below
"use strict";

/* globals run_next_test, add_test, ok, equal, Components, XPCOMUtils */
/* exported run_test */

const {classes: Cc, interfaces: Ci, utils: Cu} = Components;


Cu.import("resource://gre/modules/XPCOMUtils.jsm");
XPCOMUtils.defineLazyServiceGetter(this, "gSettingsService",
                                   "@mozilla.org/settingsService;1",
                                   "nsISettingsService");
let lock = gSettingsService.createLock();
lock.get("nfc.debugging.enbled", null);


function run_test() {

  run_next_test();
}

add_test(function test_setFocusTab() {
    run_next_test();
});

Then the test will be easily failed as timed out error
