Hi Andy,
I've managed to reproduce the exception in JENA-523, just by having an
error in the update query syntax.
I've also managed to get the concurrent modification exception triggered
by a more minimal example and without causing the exception in JENA-523,
so I'm not sure whether it's a separate issue or not.
The test queries sent to Fuseki using curl. The first and third query
return 200, the second throws the exception. I've also attached the log
output from Fuseki.
curl -v -H "Content-type: application/x-www-form-urlencoded" -X POST
--data-urlencode 'update=prefix hc:
<http://www.hebrideanconnections.com/hebridean.owl#>
insert data { hc:633 hc:associatedWith hc:633 }' \
http://localhost:3030/dataset/update
curl -v --data-urlencode 'query=prefix hc:
<http://www.hebrideanconnections.com/hebridean.owl#>
select * where { hc:633 ?p ?o }' \
http://localhost:3030/dataset/query
curl -v --data-urlencode 'query=prefix hc:
<http://www.hebrideanconnections.com/hebridean.owl#>
select * where { hc:633 ?p ?o }' \
http://localhost:3030/dataset/query
Thanks,
Stuart.

Hi Andy,
I didn't have the '--verbose' flag set when I created the logs for the
previous message so I didn't get the update query that caused the
exception. However I've tried again with verbose logging, and managed
to get the exception thrown for the select query. The queries *should*
be valid SPARQL (they're run several times in our system), but I will
get some better logs asap.
In this case, I have an update which returns HTTP 200:
INSERT {
?subject hc:associatedWith hc:633 ;
} WHERE {
?subject ?p ?o
FILTER ( ?subject = hc:90623 ) }
Then the next select query triggers the
ConcurrentModificationException in my last message.
Sorry for the vagueness. I will try to isolate the conditions tomorrow.
If I understand what's going on (and I don't :-) ...
It's the first exception that matters - the later ones are consequences
of the
17:43:33 WARN DatasetGraphText :: Exception in abort: Can't abort a

It is true you can't aborted a lock-managed transaction ... but the code
seems to include the setup (parsing the update) in the
So ...
1/ Need to find why the abort happened - the stacktrace suggested a
parse error but I'm not 100% sure.
2/ The code ought to clean up better anyway (the later exceptions).

Thanks,
Stuart.

Stuart - quick question - and from code review, not use test running
...
What was the update? Could it be that there was a syntax error in it?

Hi all,
I'm having some more problems with Fuseki and full text search. I have
an InfModel backed by a TDB dataset, which I've added a Lucene text
index to. I'm having problems with updates and select queries
resulting
in exceptions being thrown by Fuseki.
I am running Fuseki 0.2.8-SNAPSHOT 20130826-0756 which should include
the fixes for JENA-522 (where I was having problems earlier).
Unfortunately I haven't managed to come up with a complete running
example which reproduces the problem, but while I do that the stack
traces from Fuseki's log might be able to shed some light on what is
happening. I have also added the assembler file for my Fuseki set
up at
the end of this message.
After some SPARQL Update queries I occasionally get:
