Fix failing integration test (ITConnector)

[milannister]

When mvn clean verify -P integration-test is run, following test reports an error:

Results :

Tests in error: 
  ITConnector.setUp:47 » Runtime java.lang.reflect.InvocationTargetException

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0

This should be fixed.
