.getDistributedObjects call results in exception (under hzStarter) [API-1596]

.getDistributedObjects call throws the following exception **when my cluster is hzStarter** (this is our internal utility in MC team; it fires up a 3 member cluster and utilizes the data structures.)

note that the same code works fine if my cluster is an IMDG instance started via bin/start.sh.

(tested in IMDG 4.2 and latest hazelcast-nodejs-client.)

ps. ping me at will; i can show this live.
