------------------------------------
Finally done in trunk at [r1814822|https://svn.apache.org/r1814822]. To
maintain compatibility with Jr2 or older oak versions,
{{-Doak.useOldInexistenceCheck=true}} can be passed on JVM command line.
> IS NOT NULL condition for relative properties not working as expected

> It seems that a query like
> {noformat}
> SELECT * FROM [nt:base] WHERE [a/b] IS NULL
> {noformat}
> should return paths where there exists a child {{a}} without a property {{b}}
> (this works as expected)
> But, it should also return paths where there is not child {{a}} in the first
> place.
> [~tmueller], does this sound a reasonable expectation?
