3c4a3dbd7c Implemented a retry policy for tests that may randomly fail. 
Tests classes that may fail should be annotated with @RunWith(RetryRunner.class). This custom test runner attempts to re-run tests that fail, up to a maximum number of attempts defined as a constant in the test runner (currently set to 3 attempts max).

1df2b780a2 upgraded Junit version to 4.8.2. 
This brings maven build up to date with respect to ant build, which already uses 4.8.2.
It will allow implementing a retry policy for the few tests that can randomly fail, using API introduced in Junit 4.5.
