--------------------------------------
Hi Dan,
Agree, proposed way is more elegant, because RMMessageConstants is not really
fit for API package.
Improved patch is attached.

> Fix proposal: I have discovered (thanks Aki!) that there are some cases when
> oneWay response can be proceeded. Regarding Basic Profile 1.1:
> R2714 For one-way operations, an HTTP Response MESSAGE MAY contain an
> envelope.
> One-way operations typically do not produce SOAP responses. However, some
> INSTANCEs may choose to communicate infrastructure-related faults (e.g.
> MustUnderstand, VersionMismatch) in the HTTP Response message.
> In addition to this, the use of some protocol extensions (e.g.
> WS-ReliableMessaging) may create the possibility for non-empty responses to
> one-way messages. For these reasons the Basic Profile 1.1 requirement that
> the HTTP Response message not contain a SOAP envelope has been relaxed.
> I would propose to process successful oneWay responses only in following
> cases:
> A) if RM is active (check RMMessageConstants.RM_PROPERTIES_OUTBOUND,
> RMMessageConstants.RM_PROPERTIES_INBOUND)
> B) if user activate it with org.apache.cxf.transport.processOneWayResponse
> property on client.
> In other case oneWay response will be ignored by client.
> Patch is attached.
> Regards,
> Andrei.
