Make QueryResult.getNodes() work also for certain join queries
--------------------------------------------------------------
Key: JCR-2849
URL: https://issues.apache.org/jira/browse/JCR-2849
Project: Jackrabbit Content Repository
Issue Type: Improvement
Components: jackrabbit-core, query
Reporter: Jukka Zitting
Priority: Minor
There are some people who are relying on the pre- JCR-2715 behaviour where a
QueryResult.getNodes() will return a node iterator for one selector of a join
query even if the JCR 2.0 spec explicitly says that the method should throw a
RepositoryException in such cases.
For convenience and to avoid breaking such code, we might want to make the
getNodes() method work at least for inner joins (i.e. no null nodes possible)
where the SELECT clause contains just a single selector.* entry that identifies
the selector that the client is interested in.
