Andy Seaborne commented on JENA-523:
------------------------------------
1. Fuseki should separately handle the parse, which is recoverable, error
outside the actual update, which is not recoverable.
2. Transactional interface may need to indicate if abort is supported; possible
more styles of transaction than just "everything supported" and "nothing
supported".
> DatasetGraphWithLock throws exception on abort but his can occur in Fuseki

> DatasetGraphWithLock can not support a proper abort (no rollback). But some
> action, like a parse error in SPARQL Update in Fuseki, cause an abort. The
> abort there causes the internal state to become inconsistent.
