Adding a new entry under `matrix.include` section in the .travis.yml will
run test on JDK8.
for example
```
- jdk: "oraclejdk8"
env: SPARK_VER="1.6.0" HADOOP_VER="2.3" PROFILE="-Pspark-1.6
-Phadoop-2.3 -Ppyspark -Pscalding" BUILD_FLAG="package -Pbuild-distr"
TEST_FLAG="verify -Pusing-packaged-distr"
```
If the test on jdk8 does not pass, because of other modules of Zeppelin, i
suggest revert modification of .travis.yml in this PR and make separate PR and
resolve https://issues.apache.org/jira/browse/ZEPPELIN-411
