-----------------------------------

             Summary: ClassCastException while executed javascript returns Integer to js-client
                 Key: ISPN-6408
                 URL: https://issues.jboss.org/browse/ISPN-6408
             Project: Infinispan
          Issue Type: Bug
          Components: Remote Protocols
            Reporter: Anna Manukyan
            Assignee: Galder Zamarreño


In case if the javascript returns number, the execution of it over js-client, returns the following error:

{code}
Message:
     java.lang.ClassCastException: java.lang.Integer cannot be cast to [B
   Stacktrace:
     undefined

The code is: 

// mode=local,language=javascript,datatype='text/plain; charset=utf-8'
cache.size()

The verifying test is:
it('can execute a script remotely to get node address from cacheManager', function(done) {
    Promise.all([client, readFile('spec/utils/test-cacheManager.js')])
        .then(function(vals) {
          var c = vals[0];
          return c.addScript('test-cacheManager.js', vals[1].toString())
              .then(function() { return c; } );
        })
        .then(t.assert(t.exec('test-cacheManager.js'),
                       t.toBe(0)))
        .catch(failed(done)).finally(done);
  });
{code}

There is no exception on server side. Also please find below the log of the node.js execution:
