Concurrent Unit Tests

[vjkoskela]

The ArpNetworking parent pom configures the Surefire plugin to execute test methods in parallel. However, this is causing intermittent failures in StenoEncoderTest (specifically testRedactSettings). Unfortunately, efforts to locate the race condition (either in the tests themselves, or in the code) have failed. We will need to return to this issue to at least ensure there is no race condition in the code.
