> Currently we have at least one serious race condition in our pages.xml
> exception handling, related to redirect/message passing. I can
> reproduce (JIRA case is open) lost messages on exception redirect.
> Also, clean up the #{exception} and #{handledException} stuff - which
> might fix the issue as a side effect. I want one exception instance I
> can access in EL, not two. I want to be able to call getRootCause() on
> it to unwrap the root exception. Of course the root cause is the one I
> specify in pages.xml as the one that is handled, but the #{exception}
> should always be the wrapper. In any case, a clear and reliable
> (working in all situations) strategy needs to apply here.
