Description

I try to build gora under jdk1.8. I already have fixed some problems for gora-core and gora-couchdb. You can see from GORA-469 and https://github.com/apache/gora/pull/79 . But jcache map reduce test is fail under jdk 1.8. I run it with jdk 1.7 successfully. You can see fail log as follow:

java.lang.AssertionError: 
Expected :10
Actual   :0
 <Click to see difference>


	at org.junit.Assert.fail(Assert.java:93)
	...
org.apache.gora.mapreduce.MapReduceTestUtils.testCountQuery(MapReduceTestUtils.java:75)
	at org.apache.gora.mapreduce.DataStoreMapReduceTestBase.testCountQuery(DataStoreMapReduceTestBase.java:82)
	...

I've not identified problems. I detect the problem from there:

package org.apache.gora.mapreduce;

...

public class MapReduceTestUtils {

...

public static void testCountQuery(DataStore<String, WebPage> dataStore, Configuration conf)
      throws Exception {

...
    QueryCounter<String,WebPage> counter = new QueryCounter<>(conf);
...
    long result = counter.countQuery(query);
...
}
...

result is 10 under jdk1.7
result is 0 under jdk1.8

I try same test case for gora-infinispan, it is run successfully.
