[jboss-dev] Is there a reason the mvn version cannot include 2.2.1?

I'm using mvn 2.2.1, and when I try to build the embedded project its 
failing with:

[WARNING] Rule 1: org.apache.maven.plugins.enforcer.RequireMavenVersion 
failed with message:
Detected Maven Version: 2.2.1 is not in the allowed range [2.0.9,2.2.1).

When I update the version range to allow 2.2.1 the build completes fine, 
so is there a known problem wiht 2.2.1 or was this just locked down 
prior to the release of that version?
