    Description

      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();
         }
      }
      

      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:
