@cshannon Do you mean the changes in `PostOfficeImpl` and
`ServerSessionImpl`?
The added whitespace there is because of a new try-catch block in each
class, adding indentation to the lines moved into that block.
And it's all added spaces there, no tabs. IDE is also configured to use
spaces (setting coming from the imported artemis-codestyle).---
