             Summary: Not working RemoteManager.getBulk() and keySet() in compatibility mode
                 Key: ISPN-3436
                 URL: https://issues.jboss.org/browse/ISPN-3436
             Project: Infinispan
          Issue Type: Bug
          Components: Remote protocols
            Reporter: Jiří Holuša
            Assignee: Galder Zamarreño


When using HotRod client in compatibility mode, when trying to put entries via embedded cache and afterwards call RemoteCache.getBulk() or RemoteCache.keySet(), an exception is thrown. Exception is thrown in all cache modes (LOCAL, REPL, DIST).

{code:borderStyle=solid}
org.infinispan.client.hotrod.exceptions.HotRodClientException:Request for message id[3] returned server error (status=0x85): java.lang.ClassCastException: java.lang.Integer cannot be cast to [B

{code} 

Code that did it:

{code:title=EmbeddedHotRodBulkTest.java|borderStyle=solid}
public void testEmbeddedPutHotRodGetBulk() {
      Cache<Integer, Integer> embedded = cacheFactory.getEmbeddedCache();
      RemoteCache<Integer, Integer> remote = cacheFactory.getHotRodCache();

      populateCacheManager(embedded);

      Map<Integer, Integer> get = remote.getBulk();
      assertEquals(100, get.size());

      for(int i = 0; i < 100; i++) {
         assertTrue(get.containsValue(i));
         assertTrue(get.containsKey(i));
      }
   }
{code} 

Also attaching test file for this functionality.
