Marcel Reutegger resolved OAK-8207.
-----------------------------------
Resolution: Fixed
Fix Version/s: 1.14.0
Fixed in trunk: http://svn.apache.org/r1857212
Creating a read-only DocumentNodeStore on an empty nodes collection still fails
with an exception, but it doesn't try to create the root document anymore and
the exception is more descriptive now.
