I'm sorry to answer so lately. :) I wish I could give you more of the stacktrace (and I would have if I had some) but the aspects are used on an application which is launched from a service manager. This warning is the only thing that goes out of the error console. It shows at startup but I don't have more information. Do you know where or what I can start looking for ? Thanks again.
