Thanks for the remark.
A single JVM can run multiple Hazelcast instances. They are specified in
the ```<group>``` element of the configuration file.
```hazelcast.node.cluster.name``` was intended to be used as ```<name>```
value in the ```<group>``` element.
Often group and cluster names names are identical.
Indeed, current constant's name may lead to inconsistency. I will rename it
and properly document the new one.
