> 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}
