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:
