Github user ryanpersaud commented on the pull request: https://github.com/apache/nifi/pull/459#issuecomment-220753130 I made the changes that @markap14 suggested and removed unused imports that were identified by checkstyle. I've attempted to run `mvn -Pcontrib-check` on 3 different machines, but I get failures in tests for the nifi-framework-core module that seem unrelated to my modifications. For example, running the build on a Linux machine, I get the following error: Running TestSuite Tests run: 172, Failures: 2, Errors: 0, Skipped: 1, Time elapsed: 272.879 sec <<< FAILURE! - in TestSuite testStateTooLargeExceptionThrownOnReplace on testStateTooLargeExceptionThrownOnReplace(org.apache.nifi.controller.state.providers.zookeeper.TestZooKeeperStateProvider)(org.apache.nifi.controller.state.providers.zookeeper.TestZooKeeperStateProvider) Time elapsed: 24.341 sec <<< FAILURE! org.junit.runners.model.TestTimedOutException: test timed out after 20000 milliseconds at java.lang.Object.wait(Native Method) at java.lang.Object.wait(Object.java:502) at org.apache.zookeeper.ClientCnxn.submitRequest(ClientCnxn.java:1342) at org.apache.zookeeper.ZooKeeper.setData(ZooKeeper.java:1268) at org.apache.nifi.controller.state.providers.zookeeper.ZooKeeperStateProvider.setState(ZooKeeperStateProvider.java:318) at org.apache.nifi.controller.state.providers.zookeeper.ZooKeeperStateProvider.setState(ZooKeeperStateProvider.java:283) at org.apache.nifi.controller.state.providers.zookeeper.ZooKeeperStateProvider.setState(ZooKeeperStateProvider.java:228) at org.apache.nifi.controller.state.providers.zookeeper.TestZooKeeperStateProvider.testStateTooLargeExceptionThrownOnReplace(TestZooKeeperStateProvider.java:176)
