ARQ 2.9.0 is out and available from incubator.apache.org/jena
I'm afraid I don't know whether this is fixed in either that release or
in trunk. Certainly the Fuseki 0.2.1 snapshot I have which uses ARQ
2.9.0 appears to hit the issue still so if you can confirm with core
directly with the 2.9.0 code (and or the 2.9.1 snapshot) I'd go ahead
and file a JIRA for this

Hi all, I think this is a bug. The first three of the following triple
patterns are parsed successfully, but the fourth throws a runtime
exception.successfully. I'm using Jena-2.6.4 which includes with
ARQ-2.8.7. Can anyone confirm or deny this (or tell me that I'm using
an outdated version, or point me to the existing bug report that I
didn't find on JIRA,&c ;))? Thanks, //JT
