             Summary: NPE when preloading cache with DeltaAware values
                 Key: ISPN-4746
                 URL: https://issues.jboss.org/browse/ISPN-4746
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 7.0.0.Beta2
            Reporter: Gustavo Fernandes
            Assignee: Dan Berindei


{code:java}
public class DeltaAwarePreloadTest extends MultipleCacheManagersTest {

   private static final int CLUSTER_SIZE = 1;

   @Override
   protected void createCacheManagers() throws Throwable {
      ConfigurationBuilder c = getDefaultClusteredCacheConfig(CacheMode.DIST_SYNC, false);
      c.persistence().addStore(new DummyInMemoryStoreConfigurationBuilder(c.persistence()).storeName(getClass().getSimpleName())).preload(true);
      createCluster(c, CLUSTER_SIZE);
      waitForClusterToForm();
   }

   @Test
   public void testPreloadOnStart() throws PersistenceException {
      Cache<Object, Object> cache = caches().get(0);
      cache.put(1, new TestDeltaAware());
      cache.stop();
      cache.start();
   }
}
{code}

During preload, the {{NonTxDistributionInterceptor}} decides that is requires values from previous owners and tries to check if the local node is the primary owner. At this point, the WriteCH is null since no topology was ever updated. Here's the stacktrace:
