Csaba Varga created OAK-4818:
--------------------------------
Summary: Version and Version History nodes don't implement the
proper interfaces when found via Node.getNodes()
Key: OAK-4818
URL: https://issues.apache.org/jira/browse/OAK-4818
Project: Jackrabbit Oak
Issue Type: Bug
Components: jcr
Affects Versions: 1.5.10, 1.2.19, 1.0.33, 1.6
Reporter: Csaba Varga
Priority: Minor
The JCR spec says in section 15.6:
When an nt:versionHistory or nt:version node is acquired through a query or
directly through a getNode, the actual Java type of the returned object must be
VersionHistory (in the case nt:versionHistory nodes) or Version (in the case of
nt:version nodes).
While this doesn't explicitly mention the getNodes() method, I believe it's a
reasonable expectation that this method should work the same way, i.e. make the
actual Java type of the returned child object Version or VersionHistory where
applicable. Oak currently doesn't work this way; the iterator returned by
either getNodes() overload will always yield NodeImpl instances.
I will attach a suggested patch to fix this, including addition to the unit
tests to catch any regressions in the future. The patch is against the latest
trunk, but the same behavior seems to be present in all past versions as well,
so if it's not a big problem, could you also backport this to older stable
versions as well? (My employer is using AEM 6.1 currently, so we would be
interested in getting this backported to 1.2 at least.)
