Java 8 upgrade fallout and follow-ups

After upgrading from Jenkins version 2.53 to 2.54, the ec2-fleet-plugin can no longer connect to ec2-fleet nodes. Downgrading to 2.53 resolved the issue.

Does ec2-fleet plugin configuration use Java 7? I would guess so

Sorry if I was not clear. The question was about Jenkins agents being connected by the plugin.

I think you're correct. I am fairly certain the secondary ec2 fleet node's run Java 7. I'll check in a bit and add a comment.

The it is an "as designed" behavior. In 2.54 Jenkins' Java minimal requirement has been updated to Java 8, hence all agents need to be updated.
