ant build of OF: XML parsing error on file /WEB-INF/web.xml

I use a remote build system to build OpenFire.  It has built OpenFire 3.9.3 without issue.

I updated my source to 3.11.0.alpha and now I get the error/warning listed below during the build. The build process appears to continue successfully. I get this error in multiple places.

I checked the WEB-INF/web.xml file in a parser and it checks out ok.

Anybody have any thoughts on why I am seeing this error?

Thanks, Scott
