It has been reported that JBAS-1823 is not fixed.
Since the report contained no further information, I'm creating this bug report for them to fill in some details.

The only way I can see it not being fixed is if some code is doing FCI.getTargets() and then modifying
the returned result rather than updating the FCI (FamilyClusterInfo).

One obvious means of detection would be to extend ArrayList to make an ImmutableArrayList class such
that we can detect when somebody tries to modify the list of targets without synchronizing with the FCI.
Then return such a list from getTargets.
