Andrey Nechaev commented on JBRULES-2108:
-----------------------------------------
It seems there is a bug in the FieldIndexHashTableFullIterator iterator's next()
method. When a table's item contains more than one element, all the elements except
the first one are skipped. Attachement is the patch resolving the issue, and it works in
our environment.

Mark Proctor closed JBRULES-2108.
---------------------------------
Resolution: Done
The patch doesn't quite work either, but I've applied something that should do the
job. I've also added two unit tests that for this specific problem that should be easy
to update should we find any more corner cases.
