Dirk Bergstrom commented on JBRULES-909:
----------------------------------------

After changing most of the rules (to remove the last predicate expressions and tighten up some of the logic), I find this bug now affects pretty much everything.  So I disabled all the rules except this one (the simplest one):

rule "Find all PRs for user"
when
  $user : User( $reports : allReportNames, $userIsJunos : junos )
  $pr_list : RecordSet( size > 0 ) from
   collect( PRRecord( alwaysTrue == $userIsJunos || responsible memberOf $reports ) )
then
 $user.setRecords($pr_list, DataSource.GNATS);
end

This triggers the bug, when asserting PRRecord objects, or User objects.  Hopefully this will help.
