I tried to email all contributors/developers of VFS based on the list in the pom.xml. The E-Mail to Adam M. bounced (with a mail forward loop). And looking at the list of apache commiters, the id is no longer listed there. So maybe it is time to update the email address. (I would have contacted Adam directly but I cannot find a address for him).
Anyway, I also noted that Luc is listed in JIRA as the responsible person for VFS, but no Luc is in the POM.
