Looking at the examples, I do it differently.
First of all, I get the DSC using a call to GMSFactory.getGMSModule from a
separate thread. On this GMS instance I then retrieve the current (and only)
Group Handle by calling getGroupHandle - and finally on the group handle I
directly access the DSC (using getDistributedStateCache) and manipulate it
(using addToCache).
I selected arbitrary values for the "componentName" and "memberToken"
parameters of the addToCache (in my case I used "defaultCache" and
"defaultMember") - could this be the problem?

Adding ShoalLogger.level = FINER did not seem to produce any useful output.
See A.log and B.log. The warning about not being able to send a message is
still there.
