> A property index with declaringNodeTypes is sometimes used where it must not be used. Example:
> {noformat}
> /oak:index/testIndex (oak:QueryIndexDefinition)
>     declaringNodeTypes = ['oak:QueryIndexDefinition'] (Name) 
>     propertyNames = ['testProp'] (Name) 
>     type = 'property'
>     x (nt:unstructured)
>         testProp = '1234'
>     
> query:
> /jcr:root//element(*, oak:QueryIndexDefinition)[./x/@testProp="1234"]
> {noformat}
> (please note there should be more nodes, so that index is used for the query and not traversal).
> The problem is that the index is used, even thought the property is not in the node itself (of type oak:QueryIndexDefinition), but in a child node (with a different node type).
> The the index is used, and the result is empty. If the index is disabled, then traversal is used (or another index), and the correct result is returned.
