Findings:
- 32 int shifted by an amount not in range -31..31:
The shifts by 32 bits don't actually have any effect on the value
(as shown by the tests)
- possible null pointer dereference
- repeated conditional test
- field only ever set to null
All other uses of the field were to check if it was null,
which it was, so it was removed
Other actions:
- Upgrade jUnit to version 4
- Add PowerMock dependency

The client renders RDP to a window created by Java. It is important for Hyper-V support,
because Hyper-V provides access to the consoles of VMs that it is running over RDP.
