Occasionally, my application will "just start doing this" - throwing this error. I am using Wicket 1.2.4 because my application is "stuck" at that version for the time being. I do not have the time to make the changes to upgrade to the latest version, right now.
Rebooting the app server (Glassfish v2) usually "fixes" it but when it does happen, it prevents orders from going through and frustrates customers. Not a good thing...
I have no idea what causes this and don't know the internals of Glassfish to even begin to try and troubleshoot. All I know for sure is; this NEVER happened on JBoss 4.0.x with Wicket. I figured it was safe to assume this had nothing to do with my code - nowhere in the stack does it point to anything in my application (or any application running on it, for that matter.)
I realize this is vague so hopefully someone else is experiencing this and can help troubleshoot.
Here's the error:
