Subject Re: [jira] [Commented] (FALCON-2051) Falcon post-processing services are not getting invoked

Ok, let us reenable post processing sending the jms message and take up the fix in master.
  This means we will revert FACON-1926 only in 0.10 and apply to master and continue to make
the fixes in master – right?
