Description

There are several ways to create a resource object, e.g., BuilderUtils.newResource() and Resources.createResource(). These methods not only cause confusing but also performance issues, for example BuilderUtils.newResource() is significant slow than Resources.createResource().

We could merge them some how, and replace most BuilderUtils.newResource() with Resources.createResource().
