Exception when submitting a distributed task via a HazelcastClient

[sselvia]

I am getting the following exception when trying to execute a
distributed class from a HazelcastClient, when I join the member group
as a normal member or superclient then the distributed class is
executed correctly. Can a HazelcastClient submit distributed tasks?

Hi,

Sure it can.

Is the class of your distributed task in the classpath of running hazelcast?

Try running hazelcast server JVMs with
-Dhazelcast.serializer.shared=true parameter.

I figured it out, I am converting to 1.8.2 from 1.7.1 and there was a
Hazelcast.getExecutorService() call I missed. After changing that to
use the client instance all is fine. Sorry for the ooops!
