[jira] [Created] (TAP5-2133) DefaultRequestExceptionHandler swallows exceptions

Jochen Kemnade created TAP5-2133:
------------------------------------

             Summary: DefaultRequestExceptionHandler swallows exceptions
                 Key: TAP5-2133
                 URL: https://issues.apache.org/jira/browse/TAP5-2133
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.4
            Reporter: Jochen Kemnade


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.
