Description

ReplChangeManager is a singleton and it has member FileSystem object that is created during initialization and then is re-used across recycle method calls.

With doAs=true mode, this doesn't work well as the FileSystem object would have been created using a user different from the current user.
This is also leading to errors with doAs=false mode, with long running HS2 instances, as it is failing to renew the kerberos tickets (reason for this effect is unclear).
