Github user nalewis commented on the issue: https://github.com/apache/nifi/pull/2988 I grabbed the branch and attempted a clean install this morning. It failed with the following: mvn --version ``` Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T02:58:13-05:00) Maven home: C:\Program Files\apache-maven-3.5.2 Java version: 1.8.0_151, vendor: Oracle Corporation Java home: C:\Program Files\Java\jdk1.8.0_151\jre Default locale: en_US, platform encoding: Cp1252 OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows" ``` ``` ------------------------------------------------------- T E S T S ------------------------------------------------------- Running org.wali.TestMinimalLockingWriteAheadLog Tests run: 12, Failures: 0, Errors: 1, Skipped: 2, Time elapsed: 6.653 sec <<< FAILURE! - in org.wali.TestMinimalLockingWriteAheadLog testRecoverFileThatHasTrailingNULBytesAndTruncation(org.wali.TestMinimalLockingWriteAheadLog) Time elapsed: 0.014 sec <<< ERROR! java.nio.channels.OverlappingFileLockException at org.wali.TestMinimalLockingWriteAheadLog.testRecoverFileThatHasTrailingNULBytesAndTruncation(TestMinimalLockingWriteAheadLog.java:472) Results : Tests in error: TestMinimalLockingWriteAheadLog.testRecoverFileThatHasTrailingNULBytesAndTruncation:472 â OverlappingFileLock Tests run: 12, Failures: 0, Errors: 1, Skipped: 2 ``` I'm seeing [this](https://github.com/apache/nifi/pull/2819) PR that had attempted to fix this issue.
