Subject [jira] Commented: (LUCENENET-388) Exception: will crash and restart the web-application.
Date Fri, 21 Jan 2011 21:29:45 GMT


Patric Forsgard commented on LUCENENET-388:

I agree about the change that will fix my problem, now i can catch the exception and show
a friendly error message for the user. Thanks a lot for the help with the resolution.

Can it bee other places ass well that the SystemException should be changed to something else
to allow the calling code to catch the exception?

I think it should get the exception, but it should not crash the site and restart the application
each time.
