In other words, there are 4 purported members that are identified as
members of a cluster but they have not joined the group at runtime
(probably these are not started yet). Only two members join at runtime.
A call to GroupHandle.getCurrentCoreMembers() or
GroupHandle.getAllCurrentMembers() would return you the two instances
who have joined and not the 4 that were supposed to have joined.
That would be an enhancement for us. It'd be great if you can post this
into the issue tracker as an enhancement request.
