Is there a chance you could trigger this build to run using Java 7? I read up a few JIRA posts for the INFRA project in issues.apache.org and they seem to indicate that this probably will work fine with builds that use Java 7. I’m not 100% sure though.

It looks like as noted here [2] that builds.apache.org is presenting a certificate which JRE versions before JRE 8 don’t allow. The workaround presented in that FAQ is to switch the settings on the “server” which in this case would be builds.apache.org to use a different cipher list. I’m not sure, if we will be allowed to do that and I’m curious how other builds (not necessary Ivy project builds) that need to fetch something from builds.apache.org via https and JRE <=7 get past this currently. Either way, I think this is something that we will have to ask the Apache infra team for their inputs.
