There were build failures with the java 1.8 change that seemed due to flaky
tests.
https://travis-ci.org/apache/incubator-zeppelin/builds/135174837
I think we should investigate that in a separate PR, so I reverted the
change.
In the latest build, all checks succeeded except one that failed due a
flaky test tracked in https://issues.apache.org/jira/browse/ZEPPELIN-862.
