> If an exception is thrown from the try block in org.apache.tapestry5.internal.services.DefaultRequestExceptionHandler.handleRequestException(Throwable), it is swallowed without any notification. In my case, the problem was a LinkCreationListener's throwing a NPE in a redirected request originating from a previous exception. This was very hard to debug because the NPE didn't show up in any stack trace or log.
> I suggest that either the handler fail completely if the try block throws an exception or at least log it.
