Oh well, seems it doesn't work. Travis fails in bringing up Neo4j:
```
The command "neo4j-community-2.2.3/bin/neo4j start" failed and exited with
1 during .
```
And (potentially worse) on my machine, after upgrading to Java 9, I have
some issues with the ElasticSearch tests:
```
org.apache.metamodel.elasticsearch.nativeclient.ElasticSearchDataContextTest
Time elapsed: 0.77 sec <<< ERROR!
java.lang.ExceptionInInitializerError: null
