TestWebKitAPI.ServiceWorkers.ServiceWorkerAndCacheStorageSpecificDirectories and TestWebKitAPI.ServiceWorkers.ServiceWorkerAndCacheStorageSpecificDirectories are failing after bug 186806, because default session is not added to map in networkProcessProxy.
Since patch of bug 186806 is reverted and the bug is reopened, I could fix the test failure by uploading new patch there. *** This bug has been marked as a duplicate of bug 186806 ***
