Description

This was first reported by Jeff on the dev mailing list using CentOS 7 and JDK 8 (both OpenJDK and Oracle, at times) and has since also been reproduced in the Travis CI environment (Ubuntu LTS 12.04 with Oracle JDK 8, JDK 7 is fine).

The associated thread on the mailing list is available at https://mail-archives.apache.org/mod_mbox/nifi-dev/201511.mbox/[e-mail]%3E

Limited sample size suggests it is a JDK 8 issue on Linux.

Failure is:
