I posted this message [http://www.jboss.com/index.html?module=bb&op=viewtopic&t=80266] on the Seam forum the other day and identified an error message appearing in my JBoss AS startup logs that I didn't understand. My problem from that thread seems to have been unrelated to this message and has since been solved, but it seems proper to follow up on Gavin's request to repost here anyway, after my question was answered so quickly and expertly.
The message doesn't seem to affect the functioning of my application in any immediately obvious way. Please let me know if I can help you investigate it in some way, or indeed if an explanation is already known.
I should mention that the message in question is bolded in the quoted block of startup messages in the linked thread.
