-----------------------------------------
Silly question but I'm wondering WHY this was needed. The bug is not very
informative.

> 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.
