> The implementation of RowKeySetAttributeChange assumes that RowKeySet values
> of attributes can be saved off and restored at a later point in time. Reality
> is that some implementations of RowKeySet can be strongly bound to their
> model layer that basic collection operations like iterator() / addAll() would
> fail with any kind of exceptions, because between the time it was saved to
> the time it is tried to be restored, the underlying model has become stale.
> The fix for the issue is for RowKeySetAttributeChange to defensively check if
> the remembered RowKeySet is in a valid state (iterable / operable) before
> attempting to restore the customization. A similar bug was encountered and
> solved in trunk and 2.0.0.1 branch as part of solving TRINIDAD-2073. So this
> issue does not exist in those branches. I'd submit a patch over 1.2.12.5.1
> branch soon.
