Claus Ibsen commented on CAMEL-10116:
-------------------------------------
Do the exchange complete fast? As I think its due the exchange is processed
async and the await manager waits for that to complete, and where the NPE
happens is where it "stores" where the exchange current is at (by looking at
the history) and concurrently then the exchange is done, and its history is
complete.
