Subject: Followup to r1138573
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=50bac24ed9c9088b182f7e8a6e2ce1126d1c7d61;p=tomcat7.0

Followup to r1138573
Improve support for embedding Tomcat 7.

Expose the string that was used to suppress loading default web.xml as a constant. Short-circuit the attempt to load the web.xml file when this magic value is used. Thus saving us from unneeded getResourceAsStream() call.
