           Summary: [Worker] The onerror in WorkerContext should have the
                    same parameter with Worker
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: li.yin at intel.com


The Worker can register the onerror event handler like this:
worker.onerror = function (evt) {  //suppose worker is a Worker object
   //evt is a ErrorEvent object.
   ...
}

But in WorkerContext, we must use the onerror like that:
onerror = function (message, filename, lineno) {
   ...
}

It looks very strange.
>From Worker spec http://www.w3.org/TR/2012/CR-workers-20120501/#the-global-scope, 
both of them inherit EventTarget, maybe they use the same parameter should be more reasonable.
In addition the test case from Microsoft fails because of this.
