Description

We see the following test failure intermittently in travis:

[ERROR] Tests run: 32, Failures: 0, Errors: 1, Skipped: 1, Time elapsed: 13.143 s <<< FAILURE! - in org.apache.nifi.controller.repository.TestFileSystemRepository [ERROR] testMinimalArchiveCleanupIntervalHonoredAndLogged(org.apache.nifi.controller.repository.TestFileSystemRepository) Time elapsed: 0.211 s <<< ERROR! java.util.ConcurrentModificationException at org.apache.nifi.controller.repository.TestFileSystemRepository.testMinimalArchiveCleanupIntervalHonoredAndLogged(TestFileSystemRepository.java:151)

 

This appears to be a threading bug, giving that it's a ConcurrentModificationException that happens sporadically.
