Sorry for not updating. Ignazio was right, there was in fact a place where I
was updating the model within the scope of the iterator.
Silly me.

Thank you for the response and concern though.

No problem, it being something that's quite easy to do - if we had fully immutable state and functional programming languages ... then we'd have a whole category of other issues but no CME.

Erik,

Could you provide a complete, minimal example as a test case, please?

        Thanks

The CME occurs during simply iterating.

I went ahead and re-wrote the code with the
com.hp.hpl.jena.util.iterator.**ExtendedIterator<Triple>   from the
Graph.find
method.

It does seem to work, but is a bit more detailed (since it's dealing with
Triples instead of Statements.

What's the design thinking behind this restriction?

Okay, so I have a GenericRuleReasoner instance with a hybrid

configuration.

I do some SPARQLCONSTRUCT on that InfModel and then add the results back
into the InfModel.
Everything looks like it works fine.

Then I wanted to iterate over the model and compute something new

myself. Being a newbie I used


That's likely the issue. Are you adding new statements while
iterating? That's likely modifying the structures you're iterating
over, which is a lileky cause for CME.
HTH,
I.

   StmtIterator sceneIter = sourceModel.listStatements(**select);
