Scott O'Bryan commented on TRINIDAD-2445:
-----------------------------------------
I'm applying the patch now for the reverted code. It's obvious to me, though,
that some more work needs to be done so I'm going to reopen the JIRA ticket so
the final fix can be added.

> Components: Infrastructure
> Affects Versions: 2.1.1-core
> Reporter: Arjun Vade

> Any exceptions from the Trinidad code that runs before JSF lifecycle that
> propagates to application server layer may result in the end user not seeing
> a meaningful error message in UI.
> Solution: Trinidad code that runs before the JSF lifecycle shouldn't allow
> exceptions to propagate out of the ServletFilter.
> The fix is simply to add code to our various ServletFilters to trap the
> errors at that point before the errors propagate out.
