A build failure was reported, whose  root cause is that the central (http://repo2.maven.org/maven2/javax/mail/mail/1.4/mail-1.4.pom) and the source of the repository (http://maven.glassfish.org/content/groups/public/javax/mail/mail/1.4/mail-1.4.pom) have different POMs. So if your local repository was pre-populated with JavaMail from central you get this error.

Relaxing a rule a bit.

[FIXED JENKINS-6795] Maven agent needs a fix for the 'hardcoded' socket connection to localhost, perhaps a fallback mechanism when it fails to connect through the loopback interface can solve this pesky issue?

It actually contains one hunk that is necessary, but I'll merge it from
the 1.408 branch.
