> RuleCleanCriteria may not be adding in RuleRaiseNull when needed, which can result in invalid nodes under an accessnode.  This in turn may manifest itself as:
> java.lang.ArrayIndexOutOfBoundsException: -1
> 	at java.util.ArrayList.elementData(ArrayList.java:338)
> 	at java.util.ArrayList.get(ArrayList.java:351)
> 	at org.teiid.query.optimizer.relational.rules.RuleCollapseSource.buildQuery(RuleCollapseSource.java:338)
> 	at org.teiid.query.optimizer.relational.rules.RuleCollapseSource.buildQuery(RuleCollapseSource.java:373)
> 	at org.teiid.query.optimizer.relational.rules.RuleCollapseSource.createQuery(RuleCollapseSource.java:228)
> As there may not be from clause items to collapse.
