Key: GADGETS-71
URL: https://issues.jboss.org/browse/GADGETS-71
Project: Gadget Server and Gadgets
Issue Type: Bug

This exception occurs periodically when starting up the gadget server and adding the gadgets to a page. It appears to be related to the service overview gadget, as that does not display any content when this exception occurs.
