-------------------------------------

             Summary: Regression RuleCleanCriteria
                 Key: TEIID-2041
                 URL: https://issues.jboss.org/browse/TEIID-2041
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.7
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 7.7.1, 8.1

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.
