Andy Seaborne commented on JENA-260:
------------------------------------
Alex - thanks for the report.
The transaction has commited - the exception is caused after the commit point.
The data is safe.
The message is from Fuseki consistency checking.
This needs fixing as soon as possible.
Fuseki is calling the clearup "end" at the wrong point. I have put in a
workaround fix in Fuseki and woud be grateful if you could confirm or deny it
works. I have just scheduled a complete development build so the snapshot
repos will be corrected in a few minutes.
TDB needs a changing as well to be more robust again this easy-to-do call
pattern. There will be a related set of circumstances in API code.
