Subject [16/22] git commit: updated refs/heads/master to 443acac
Date Fri, 14 Feb 2014 17:38:16 GMT
Fix findbugs findings in cloudstack-service-console-proxy-rdpclient

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
