PR for this change.

> When trying to execute Thread's derived class implementing IgniteRunnable 
> using compute API, it silently serializes to null because Thread 
> serialization is prohibited in MarshallerExclusions and throws NPE on 
> executing node.
> We need to throw more informative exception for such case.
> Reproducer in the attachment.
