Simon,
You running a 32 bit JVM?
You are trying to stop a long running query from another thread?

Hi,
what I do:
open a TDBFactory.createDataset()
run a sparql query that runs a long time
then the execution gets interrupted by a Thread.Interrupt exception.
Why is the thread being killed with Thread.Interrupt? Killing threads
this way is not supported - it is likely to put the internal state of
the system into an inconsistent state.
Jena ARQ supports clean to stop queries via QueryExecution.abort() and
also via query timeouts.
/** Stop in mid execution.
* This method can be called in parallel with other methods on the
* QueryExecution object.
* There is no guarantee that the concrete implementation actual
* will stop or that it will do so immediately.
* No operations on the query execution or any associated
* result set are permitted after this call and may cause exceptions
to be thrown.
*/
This works by calling down the stack of operations currently executing
the query and allows them to exit at the first moment they are able to.
Interrupting OS system calls is not supported.
