The significance of root context
I am trying to understand the significance of the "root" context in TC 3.2.
It seems that when no root context is defined i.e. when nothing is mapped to
"" path and
an unavailable resource is requested by a client, tomcat takes up 100% CPU
time and does not let go.
Must I always map some directory to the root context?
Steps to reproduce behavior in the standard TC 3.2 distribution:
* In server.xml comment out
<ContextInterceptor className="org.apache.tomcat.context.AutoSetup" />
(this has the effect that the webapps/ROOT is not mapped to "").
* Start TC
* Connect to http://localhost:8080
Note: the same behavior can be seen if webapps/ROOT is removed.

The patch was sent as an attachment.
Here it is again, this time as "diff -u" instead of "diff -c"
and I have forced it to plain text only instead of both plain text
and html.
Hopefully that will come through ok.
Let me know if you still have any problems.

Shawn,
Would you please re-post the patch. Provide the output of cvs diff -u as an
attachment this time. Your previous post included the patch embedded inside
the email (which was HTML formatted) and was almost unreadable.
