When using a salesforce operation after an aggregator, control seems to return to the aggregate caller immediately instead of proceeding with processors downstream from the salesforce operation. This is the behavior I'd expect if using the aggregator with parallelProcessing.
I believe this is longstanding behavior, however with the removal of the `synchronous` option from the salesforce component (
CAMEL-14138), we've removed a workaround to this issue.
I'm seeing the same behavior with a salesforce operation via a wiretap with a threadpool with poolsize, maxsize and queuesize of 1, which should effectively behave in a synchronous manner.
