Hi Craig, I also received only this email (and I'm a moderator of the dev@ list, so the message never made it into Apache's infra)
When this issue was first reported [1][2] I asked on the Maven mailing list what's going on [3]. I think this JIRA contains the most information on the issue: https://issues.apache.org/jira/browse/MNG-5899 It doesn't seem that Maven is going to fix the issue anytime soon. One idea I had regarding this issue was to print a warning in the maven output if we detect Maven 3.3 at build time.
