Returns 500 for a non-existent resource, should return 404
----------------------------------------------------------
Key: WW-2673
URL: https://issues.apache.org/struts/browse/WW-2673
Project: Struts 2
Issue Type: Bug
Components: Plugin - REST
Affects Versions: 2.1.2
Environment: WAS 6.1 on WinXP64
Reporter: Michael Watson
Priority: Blocker
When I request an existing object via the REST plugin it is returned ok.
However, requesting a non-existent resource should return a 404 (page not
found) to be truly REST-ful. What I get instead is a 500 error and this not
very helpful stack trace:

The problem seems to be that nothing goes on to the valuestack (correctly since
the resource doesn't exist) but whatever is trying to read from the valuestack
barfs because it's empty.
