Reproduction steps

I am going on a blitz here and running a consul server agent in dev mode, a vault server in dev mode and attempting to get nomad running in dev mode on my workstation.

I downloaded the nomad 0.6.3 binary as well and got the same result.

matthew@precision-5520:~/Workspace/vault-tutorial$ vault version
Vault v0.8.3 ('6b29fb2b7f70ed538ee2b3c057335d706b6d4e36')
matthew@precision-5520:~/Workspace/vault-tutorial$ consul version
Consul v1.0.0-beta1-beta1 (82f312d)
Protocol 2 spoken by default, understands 2 to 3 (agent will automatically use protocol >2 when speaking to compatible agents)
matthew@precision-5520:~/Workspace/vault-tutorial$ nomad version
Nomad v0.7.0-beta1

Hi this is a duplicate of https://github.com/hashicorp/nomad/issues/3324 - we are working on a fix to Consul (-beta2) that should be released tomorrow.

Here's the Consul beta2 release which fixes this behavior - https://groups.google.com/d/msg/consul-tool/qrdTkFVEBFQ/3hIunM91AAAJ.

@slackpad Updating to the beta 2 of Consul 1.0 worked. Cheers!

Thanks for the update! I'll leave this open to see if the Nomad folks want to change that panic to an error on that side, just to harden that side.
