I should have thought of that, sorry. Unfortunately (fortunately for me), I 
don't see the error anymore. Lots of things changed in the mean time 
(source code and db schema) as this project is under heavy development. 
Yes, I could go back-trace using my repository and maybe make it fail 
again, but time is a scarce commodity, so I choose to continue development.

I did notice one anomaly the day it happened, not sure it's related to the 
issue; I had a copy of a src directory under my WEB-INF folder, (I blame 
eclipse, but who knows, could have been user-error; me), which I deleted. 
I'll make sure to capture the payload if I see this again.
