Exception While Calling Process with Instance Clean Up Configuration

[bala ajanthan <ba...@gmail.com>]

Hi devs,
I am getting following exception[0] while calling a BPEL process(with
couple of partner services) with instance clean up enabled on success with
all categories(instance,variables,correlations,events and messages) .

If I remove messages from the configuration it is working with out the
exception.

As I dig into the code more I found out that the MessageExchange is deleted
whenever INVOKE activity finished[1] but.When ever the instance is
persisted before cleaning up, the above exception is thrown because of
MessageExchange is deleted.

Is it correct to delete the message exchange whenever INVOKE activity
finishes even-though the whole process still running and we do not know the
status(success or failure) of the process yet?
Or else am I missing something here?Can you please somebody clear it for
me?

Thanks.
