Sounds right.

Yep. So the line you put above is correct to pause it.

Ah. I see the confusion..
Around line 65, you see that the OutgoingChainInterceptor grabs the out
message from the exchange and then sets up the outgoing chain and has that
chain process that message.
In your case, it's likely that the out message is null since the fault was
thrown before it would have set that up. Take a look at the block that stars
around line 64 of the ServiceInvokerInterceptor (same package). That's
where the out message would normally be setup. Obviously, the
MessageContentsList that it sticks in that message would contain your custom
result bean.
