The travis test run for Java 8 failed while it passed for Java 7. It fails
in a test for HBase 1.2, which is not affected at all by this change. That
indicates that the failing test case is flaky. I created a new Jira TEPHRA-253
to track the flaky test.
Since that failure is due to a flaky test, and it passed with Java 7, and
the changes here do not have any influence on the failed test, I am confident
that this change did not introduce the failure. Hence I will commit this.
