An: OASIS Java
Betreff: RE: [sca-j] NEW ISSUE: Redirecting callbacks
The changes made in the Assembly TC F2F gave the Java TC the freedom to
either remove this redirection or not remove it, as we choose. I would
choose to remove it.

RE: [sca-j] NEW ISSUE: Redirecting callbacks
+1 and I thought we already nixed redirection of callbacks in the Assembly
TC at the F2F (The resolution of Assembly issue 4).

RE: [sca-j] NEW ISSUE: Redirecting callbacks
+1
Redirection of callbacks is another of those edge cases that would make
our specs appear overly complex. I would be in favor of nixing it.

Re: [sca-j] NEW ISSUE: Redirecting callbacksLink
Folks,
Notwithstanding the discussion that has already taken place on this new
issue (& it would be nice to have a
number to refer to !):
Can I ask what is really intended here, please? In other words, can you
outline the function that you are trying
to allow (merely removing a sentence does not get at that).
I'd be more in favour of removing the capability of redirecting the
callback at all. This is one of those pieces
of complication that are in the 0.1%, not even the 20% case. What do we
lose if we remove the capability
altogether?
Allowing an alternative callback raises all these nasty questions about
the nature of the replacement callback
and its lifecycle, for which I know of no simple answers. Forget the
implementers of runtimes for a moment, let's
think about how you explain this capability to the end users. What
expectations and obligations do those
folks have if they utilise this capability?
Yours, Mike.

[sca-j] NEW ISSUE: Redirecting callbacks
RAISER: Michael Rowley
TARGET: Java Common Annotations and APIs, section 6.7.5 Customizing the
callback
DESCRIPTION:
The last paragraph of this section says:
A callback object may be a service reference to another service. In that
case, the callback messages go directly to the service that has been set
as the callback. If the callback object is not a service reference, then
callback messages go to the client and are then routed to the specific
instance that has been registered as the callback object. However, if the
callback interface has a stateless scope, then the callback object must be
a service reference.
The second sentence of this (saying that ?... callback messages go
directly...?) is overly constraining has complex and confusing
implications for runtimes.
PROPOSAL:
Remove the second sentence from this paragraph.
