Hi,

Since updating from 0.15.0 to 0.15.1 I'm getting the following warning  
when startin up ES:  
[WARN][jmx] [Leader] Could not register object  
with name: {elasticsearch}:type=Leader [elasticsearch\_KUw-  
jkNURHi05sfMgKVlGQ],service=indices,index=twitter

I'm getting this on OSX and Ubuntu.

Reproduce:

- Start ES
- $ curl -XPUT [http://localhost:9200/twitter/user/kimchy](http://localhost:9200/twitter/user/kimchy) -d '{"name" :  
"Shay Banon"}'
- Stop ES
- Start ES

I have no idea what it means, so I thought I'd just post it here..

Sincerely,  
Reto

It means that it failed to registered itself with JMX (which is a JVM thingy that exposes information, elasticsearch registers itself with some specific elasticsearch metrices). I think its because it uses a name that is malformed, I will check and report back.
