As per the Apache post, I verified that the application is doing no request
wrapping, and can only assume that Stripes is.
2012-01-23 13:50:03,714 ERROR [org.apache.catalina.core.ContainerBase.
[jboss.web].[localhost].[/].[StripesDispatcher]] (ajp-144.226.221.212-8009-1)
Servlet.service() for servlet StripesDispatcher threw exception
java.lang.StackOverflowError
at
org.apache.catalina.core.ApplicationHttpRequest.getAttribute(ApplicationHttpRequ
est.java:220)
at
The other consideration is that there is a bug in JBoss (not impossible I'm
sure) which is causing it.
I'm still working on getting the beginning of the stack trace, but it's tough
because not all the log lines are printed. My next step is to put a filter in
front of Stripes and attempt to capture HTTP headers and params in order to
narrow down the scope of the triggering event.

calls getRequest().getAttribute(name). The very next stack frame points, again,
to line 222 of the same file. That indicates that the wrapper has somehow
wrapped itself. I have no idea how that could happen.

you know how to reproduce the problem, would be to put together a small test

there might be someone on the list who would find this interesting enough to
tackle with a little direction.
