             Summary: Marshalled value is returned while executing javascript and returning value from cache over HotRod client
                 Key: ISPN-6411
                 URL: https://issues.jboss.org/browse/ISPN-6411
             Project: Infinispan
          Issue Type: Bug
          Components: Remote Protocols
            Reporter: Anna Manukyan
            Assignee: Tristan Tarrant


When trying to execute a script over hotrod-client, which puts some data to the cache and returns it, the test fails with the following exception:

{code}
java.lang.ClassCastException: [B cannot be cast to java.lang.String

	at org.infinispan.client.hotrod.ExecTest.testRemoteScriptRemoteExecution(ExecTest.java:122)
	...
{code}

The test code and javascript code are:
{code}
@Test
   public void testRemoteScriptRemoteExecution() throws IOException {
      String cacheName = "testRemoteScriptRemoteExecution_REPL_SYNC";
      ConfigurationBuilder builder = getDefaultClusteredCacheConfig(CacheMode.REPL_SYNC, true);
      builder.dataContainer().keyEquivalence(new AnyServerEquivalence()).valueEquivalence(new AnyServerEquivalence()).compatibility().enable().marshaller(new GenericJBossMarshaller());
      defineInAll(cacheName, builder);
      try (InputStream is = this.getClass().getResourceAsStream("/test1.js")) {
         String script = TestingUtil.loadFileAsString(is);
         clients.get(0).getCache(SCRIPT_CACHE).put("testRemoteScriptRemoteExecution.js", script);
      }

      Map<String, String> params = new HashMap<>();

      String result = clients.get(0).getCache(cacheName).execute("testRemoteScriptRemoteExecution.js", params);    //<- The exception is thrown here while casting to String
      assertEquals("hoptimus prime", result);
      assertEquals("hoptimus prime", clients.get(0).getCache(cacheName).get("a"));
   }

//test1.js
// mode=local,language=javascript
cache.put("a", "hoptimus prime");
cache.get("a");
{code}
