--------------------------------------------------------------------
Hi, i was playing with this yesterday and incurred in the same exception. It
seems to appear only when using the oak run modes. It seems that with the
changes in revision #1674625 that issue is gone.
There's another couple of problems though. One is simple enough, the dependency
on org.apache.sling/org.apache.sling.jcr.resource/2.5.0 causes
resource.getPath() to return double slashes ("//foo") for each node under the
root, and I have replaced it with
org.apache.sling/org.apache.sling.jcr.resource/2.5.1-SNAPSHOT since the problem
is fixed in the trunk.
The other is a little bit more complicated. In oak run modes, I see this
exception in the logs when sling start:

I tried to solve it by adding, in oak.txt, the following configuration:
{noformat}
[configurations runModes=oak]
...
org.apache.jackrabbit.oak.plugins.index.lucene.LuceneIndexProviderService
localIndexDir="sling/oak/repository/index"
{noformat}
but the exception still happens at startup. On a positive note, though, it
looks like the configuration get installed (after the exception), and then you
can see in the logs:
