Hi Holger,
There are currently five patches attached to the JENA issue. Is this the
patch that you tested JENA-120-r1173178.patch?
Or as an other option would you like me to test the jena-arq 2.8.9
SNAPSHOTS and jena 2.6.5 SNAPSHOT? If this could be interesting for you
its fine by me as we are still in prototype stage.
Regards,
Jerven

Hi Jerven,
this is a Jena/ARQ bug, see
http://mail-archives.apache.org/mod_mbox/incubator-jena-users/201109.mbox/%[email protected]%3E
The mail above contains a link to a simple patch to ARQ that will fix it. Let
me know if you have trouble applying the patch.
Regards
Holger

Hi Holger, All,
I am getting the following exception when using two threads to run
SPINConstraints.check() on different ontmodels.
As on the same data/code this exception happens on different places I am
worried about thread safety. Should the spin API be threadsafe for this
operation? I did not see any note in the javadoc of SPINConstraints [1].
If yes I will need to work on getting a test case out to the ARQ developers.
Thanks and regards,
Jerven
