Error in 'JiraActionFactory' prints horrible message on the screen instead of taking you to the 500 page.

If you enter in URL that points to an action that does not exist (e.g. secure/project/ViewProect.jspa) you get a strange page with:

"HTTP Status 404 - Could not execute action [ViewProect]:Action 'ViewProect' not found or could not be initialized a class with that name could"

I think you should get a 500 page instead of this random and badly formatted error message. A 500 page is displayed if you put in a bad command name (e.g. jira/secure/project/ViewProject!dhdhdh.jspa).
