    Is this an L1 Cache inconsistency issue?

      Hi all,

       

      I'm currently testing ISPN (ISPN 5.1.0.CR1) as a distributed cache which means that by default I have the L1/Near Cache enabled and during my tests I faced a weird issue that sounds like an inconsitency issue. See below the unit test to reproduce:

       

       

         public void testConsistency() throws Exception
   {
      GlobalConfiguration gc = GlobalConfiguration.getClusteredDefault();
      gc.fluent().transport().addProperty("configurationFile", "udp.xml");
      Configuration c = new Configuration();
      c.fluent().clustering().mode(CacheMode.DIST_SYNC).hash().numOwners(1).transaction()
         .transactionManagerLookupClass(GenericTransactionManagerLookup.class);
      EmbeddedCacheManager cm1 = new DefaultCacheManager(gc, c);
      EmbeddedCacheManager cm2 = new DefaultCacheManager(gc, c);
      Cache cache1 = cm1.getCache();
      Cache cache2 = cm2.getCache();
      KeyAffinityService keyAffinityService =
         KeyAffinityServiceFactory.newLocalKeyAffinityService(cache1, new RndKeyGenerator(),
            Executors.newSingleThreadExecutor(), 100);
      Object localKey = keyAffinityService.getKeyForAddress(cm1.getAddress());

      cache1.put(localKey, "foo");
      assertEquals("foo", cache1.get(localKey));
      assertEquals("foo", cache2.get(localKey));
      cache1.put(localKey, "foo2");
      assertEquals("foo2", cache1.get(localKey));
      assertEquals("foo2", cache2.get(localKey));
      cache2.put(localKey, "foo3");
      assertEquals("foo3", cache1.get(localKey));
      assertEquals("foo3", cache2.get(localKey));
   }

       

      Could you please tell me if it is a bug? If not could you please tell me what's wrong with my code/configuration?

       

      Please find as attached file the source code of my test case.

       

      Thank you in advance for your help,

      BR,

      Nicolas
