This is a regression caused by a recent fix I made to this class (master commit e68540f).
Setting to Urgent since it blocks 819145. I would expect that this issue should also be cloned so we have bugs targeting JON3.1.0 and RHQ4.5 Ian, I see a commit into master for this BZ (http://git.fedorahosted.org/git/?p=rhq/rhq.git;a=commit;h=1504ec41d2b9dc2e31526e619e150dfacffe474c). What's the status?
http://git.fedorahosted.org/git?p=rhq/rhq.git;a=commitdiff;h=1504ec4 fixes this in master.
Bulk closing of items that are on_qa and in old RHQ releases, which are out for a long time and where the issue has not been re-opened since.
