It is an artifact from the primordial version used to restart the JSR.
In researching this a bit, I noticed that the javadoc for all of the
createContextualProxy(...) methods says that contextualized objects are
useful when "communicating with component instances on different Java
processes." That would seem to imply the ability to serialize context
to jvms other than the application server, is that really what we
wanted to say?
