Andy Seaborne commented on JENA-2294:
-------------------------------------
This affects updates to the database after tdb2.xloader has run.
The database produced by tdb2.xloader is valid for query but not for subsequent
updates.
> tdb2.xloader creates invalid database - later update causes wrong answers.
