Jukka Zitting resolved JCR-2933.
--------------------------------

       Resolution: Fixed
    Fix Version/s: 2.3.0

Thanks! I committed the latest patch in revision 1092683. (I assumed the truetrue was a typo,
and removed it. :-)

I'm resolving this as fixed. Let's use followup issues for any further fixes and other improvements.

> n1.setProperty("n1prop1", "page1");
> def n2 = n1.addNode("node2", "sling:SampleContent");
> n2.setProperty("n2prop1", "content1");
> Execute this Query:
> Select * from [sling:SamplePage] as page left outer join [sling:SampleContent] as content
on ISDESCENDANTNODE(content,page) where page.n1prop1 = 'page1' and content.n2prop1 = 'content1';
> The resultset have 1 row with 2 Nodes. This OK.
> Then execute this:
> Select * from [sling:SamplePage] as page left outer join [sling:SampleContent] as content
on ISDESCENDANTNODE(content,page) where page.n1prop1 = 'page1' and content.n2prop1 = 'XXXXX';
> The resultset has 1 row with 1 node.
> This wrong. The result should be 0 rows.
> Old Versions, prior 2.2.2 have also 0 rows as result.
> Also, if nodes "n2" not exists, jackrabbit reports 1 row as result.
