Early on, we decided to make context always a parameter to remotable methods. If the caller passed a context, we'd use that, and if not, we'd use the one stored on the object if possible. That has been not that useful, and also a source of infinite confusion for people learning the code. One of the work items here is to remove that ambiguity and require that the object have an embedded context in order to make any remotable calls. Change-Id: I6ee4404f3b16c5cb8db93db13eb75e1aa1a3c146
